Just so everyone knows, the audio clips of the exhaust from the rear were normalized to a LOWER dB level so your headphones don't blow out, and so you can hear the full range of the tone! Thank you everyone for the support

[@jaycruz6304]

Did you use the Cobb ots tune or did you get a protune? I just wanna make sure that if I get the grimspeed jpipe will it work with the Ots map

[@WRXGarage]

In this video I used the Cobb OTS stage 2 tune. Definitely go watch our video on the etune process I did afterwards.

[@oaguirre013]

For your headlights did you change out the whole assembly or just swap out the bulbs?

[@WRXGarage]

Kevin's headlights have blacked-out housings, added switchback c lights, and also a full led bulb replacement. It's all the original housing/assembly. They were opened up, painted, c light installed, then resealed!

[@oaguirre013]

Thankyou. Any links to the bulbs you used?

[@WRXGarage]

I used the Katana LEDs from Amazon! H11 for the low beams and fogs, and 9001 for the highbeams. They have a great rating on bulbfacts.com and are specifically designed for projector style headlights!

[@WRXGarage]

You're asking about the silver car right?

[@oaguirre013]

Yeah thanks alot. Just picked up a 2020 wrx same color and cant stand the stock headlights my daily drive is on backroads and at night cant see much of what's infront of me

[@WRXGarage]

There's going to be drone with any option you choose with an aftermarket jpipe. Anyone that tells you otherwise is lying... That being said, some will have way more, like single exits or non-resonated midpipes. Q300 will be the most quiet/least drone thats still louder than stock. Imo, it might be too quiet for you.

@@WRXGarage would you get a resonated or non resonated catted J pipe with the R400?

grimmspeed catted is definitely the best catted downpipe for the FA20. I have the tomei single exit and perrin heads paired with it and it sounds amazing! I have a catted and catless comparison on my channel! Nice work!

I have a Invidia J pipe and Q300 on WRX, when I installed the J pipe I didn't have any heat wrap so I massaged the OEM heat shield and it secured using the O2 sensors.

[@hecmeister]

Love the video. I too was looking to go Cobb all the way. I was worried it would be too quiet! I think you've talked me into going this route. I want a little more growl out of my exhaust; and more power. I was super geeked when I loaded the Stage 1 firmware. I can't WAIT to see what happens when I change out some hardware and retune. Thanks again!

[@WRXGarage]

🤘

[@dlg5485]

Nice video. It's interesting to learn that this aftermarket cat is more effective than the stock one. I definitely wouldn't have expected that. I just purchased a 2020 WRX Limited and I had ruled out any major exhaust mods for that reason, but maybe I'll consider something like this after all. However, that'll be a ways down the road because this car was way too expensive to risk losing my warranty. I do plan to upgrade the shifter stop and bushing immediately, but other performance mods will have to wait.

[@WRXGarage]

👍

[@jomardiaz78]

if you let it roll while in 1st or 2nd gear (Clutch in) rev it, you get to hear all the cool different pops. depending on how much you rev, gives you different's amount of aggressive pops. I have a catted jpipe and remark cat-back exhaust, resonated

Thank you sir! Your videos give me all the info I need to make my choice! Because of you I'm also going with the Invidia R400 for my WRX 2019! No offense towards Kyle's Axleback! But I live in Quebec (Canada) and the exhaust laws here ARE CRAZY

[@WRXGarage]

Exhaust laws in the US are very, very gray. Meaning a lot of states have them, but they're rarely enforced unless the car is absolutely obnoxious or speeding. California is definitely strict too.

[@Enerix87]

@@WRXGarage Exhaust and tinted windows are very gray indeed , it all depends on the cop who see's you sadly. Good to know that it isn't only in Quebec! Back in the day I had a 1995 DX Honda civic... my stock muffler broke... called up this scrap yard, guy says i have the perfect fit for your car...They guy installed a fucking honda prelude exhaust kit cause he one sitting around , costed me 50$ But man.... literally sounded like a huge lawn mower lol!

[@gerardomadera139]

Would you recommend being able to run other down pipes with Cobb tunes? I hear people say use only Cobb tune with Cobb parts but I want to know if I can use any decatted or catted j pipe I want? I’m new to Subaru

[@WRXGarage]

Most aftermarket catted jpipe's will be fine with a COBB OTS tune, it just won't be optimized. I'd definitely recommend that you don't try it with catless.

Nice, congrats on the install 🙌 Killer deal on the j pipe too! I really need a catback. Car sounds great with the r400, grimmspeed combo. I'm j pipe with stock catback and its aight I guess, kinda raspy though. Stay safe put there, and keep up the GREAT content!! 🤙🏼🤙🏼🤙🏼

[@saigoneze4746]

Im trying to figure out whether to get the invidia j pipe or another brand I dare say there all pretty similar .Will also do the egr/tgv deletes while at it .Keep the wrx vids coming man!

[@WRXGarage]

To be honest, you're right most of the jpipe's are similar. Grimmspeed's has a different location for it's cat, further down the pipe which supposedly helps with exhaust velocity. cobb's ends with a 2.5" or 2" flange instead of 3". Other than that... They're all very similar. When going for it, don't give in to the cheapest out there. Trust in the name brands who produce the best quality products.

[@brianandrade7276]

Do you need a tune to have the j pipe or can you have it stock?

Aftermarket jpipe needs a tune!

[@danielo22]

About to purchase the gs catted downpipe. Did you have to do any other mods to go stage 2 besides the downpipe. EGR/TGV delete,etc... Is it a necessity? Really enjoy your videos btw, very helpful and informative.

[@WRXGarage]

For the WRX, no other mods are technically required to safely go "stage 2". If you just want to do the GS jpipe and get tuned for it, that's completely fine! If you plan on getting an etune or protune, I'd suggest adding atleast the GS ebcs as well, just for more reliability and control.

The studs are the only scary part tbh. Make sure you have some cobalt drill bits in case you have to drill anything out

[@xNo0meansYesx]

Adding another comment, on cold starts with the GS v2 and Invidia r400. It's loud outside but inside the house I cant really hear it. I live in a highly populated area. My neighbor (old head in the 70s, me being late 30s) said my car sounds great while he was getting into his car. Driving around without getting on it, sounds great and will not impede your conversations with people. Getting on it with windows up is quiet in the cabin but loud enough to know you got on it.

[@josephc259]

I have a GS v2 with Invida R400 and love how it sounds. The recording microphone picks up more than what it is. Cold starts are loud but give the oil a chance to circulate then roll off. My son and I prefer having the windows down while driving so we can enjoy the exhaust. While the windows are up my music volume is at about 12 and I can hear it clearly.

[@Snipurss]

I have the same catback, not planning on getting a downpipe + intake + tune any time soon but this makes me want to lol

[@csw1190]

Dude I would love that level video for the exhaust! Y’all are always great to watch! I was on the fence of what down pipe between grimspeed resonated and not resonated and I’m pretty sure you made my mind up

[@WRXGarage]

Yeah we definitely will in the next couple weeks. Just so you know though.. GS doesn't make a resonated j pipe version, unless you're talking about their catback

[@csw1190]

WRXGarage well the mid pipe portion yea. What is your full set up on that turbo back it’s a r400 with mufflers and an open mid pipe and a catted j pipe right ?

[@WRXGarage]

I explain the full turboback setup near the end of the video, when we're sitting in my car!

[@csw1190]

[@macharmon3834]

I have a the grimmspeed catted j pipe and I just ordered the r400, do I need any adapters at all or are the gaskets that came with the j pipe alright? I’m currently waiting to install it all at once and get a pro tune shortly after. Seriously looking forward to your response as I’m new to this 😅

[@anirudhghanta6]

Love this Video. That exhaust sounds amazing. I have a stock 2019 wrx and did a stage 1 tuen with cobb accessport to decrease the rev lag from 1st - 2 nd gear. I want to go to stage 2, can any one please help me with what I would need other than Invidia r400 and a j-pipe/downpipe. Thanks

[@WRXGarage]

You'll need new gaskets and hardware!

[@warsonmedia]

My recommendation would be to get the Jpipe, Intake, EBCS, and an eTune from www.getmtuned.com. You could run his E30 tune if you have access to Ethanol. It would be a whole new car.

WRXGarage I’m 415/380 on E60. MTuned is where it’s at man. www.getmtuned.com. I’ve been tuned by 6 different guys and Mike Adkins is the best.

[@jameskocks4734]

i cut off the resonator of the r400 and it sounds better.

[@troyspurvey928]

I asked Cobb if I could use another Jpipe besides theirs and they said they wouldn’t reccomend it, what jpipe options do I have that will for sure work with the ots stage 2 ?

[@WRXGarage]

Catted only. COBB's tune is technically designed for only the COBB catted jpipe, but you'll be able to safely run their tune temporarily with any brand name catted jpipe. Again, the tune itself won't be the best because it's not exactly designed for your jpipe, but overall, it will be safe and pretty reliable. An etune or protune will always be better.

[@shatrel7117]

What shift knob is that ?

[@WRXGarage]

Raceseng slammer!

[@KevinMoto719]

So you just used a cobb ots tune with your gs jpipe? How is that, my impression was that it would only run with a cobb downpipe. What brand cold air do you have?

[@WRXGarage]

I have a stock intake! And actually, you can run pretty much any catted downpipe with Cobb's stage 2 OTS! Not the most reliable thing in the world, but it's safe enough to run for daily driving no problem

[@phiL_2022]

Realistically how loud is it during cruising and highway speeds? I went from a straight pipe to now catless dp with stock exhaust lol want to keep it as quiet or even a hare louder than it is now

[@WRXGarage]

This entire setup is probably in the middle of the pack for loudness. If I were you, I'd go for the q300 catback instead. I think that would meet exactly what you're looking for. The r400 is a couple steps louder.

[@domingopoupin7653]

How does this compare in sound to just an axleback muffler delete with the stock j pipe?

[@WRXGarage]

It's definitely louder and wayy deeper! The overall sound quality is better too.

[@youngdrug5927]

I just Bought 1 in BC, Canada. I bought the sport variant. I feel that the car’s really lacking below 1800 rpm. It’s manual.It’s faster than my Octavia vrs which had 310 hp with a stage 1 tune. It does not feel fast but. Please suggest a tune which would give me more low end torque. The vrs has sport dct from audi and brakes from the cayman. I am very new to North America. Also, I’ve never owned a Japanese car. Please help. Thanks.

[@WRXGarage]

To be honest, you should NEVER go more than half throttle below 3000rpm anyways. No well-tuned car will have good power that low in the rpm band! Also, keep in mind that these cars are turbocharged so the powerband peaks at around 5500 in every gear

[@connordunckel6905]

I don't even let mine cruise at that low of an rpm

[@JALNIN66]

I just bought a 2019 WRX with this exact combination. I already got pulled over by a MA state trooper for just maintaining the speed limit on the highway. Just driving by, no extra revs or acceleration. He let me off with a warning because I just bought it and I passed inspection last week. This was only 2 miles from my house so I think he's going to be looking for me from now on. My last car was a stock G37 and in 5 years I never got pulled over. I need to either quiet this thing down significantly or sell the car. He quoted me the MA law that states aftermarket exhaust may not be any louder than stock. Total BS as I could buy a Hellcat that would be just as loud but that's OK? Why because I spent a lot of money? I watched your Q300 video but I think that's still loud enough to get me pulled over constantly. Apparently my J-Pipe adds a lot of volume by itself. What's the quietest possible exhaust that will not require a retune? I have a protune with TGV and EGR delete, BRZ intake and flex fuel mods, all of which COBB recently stopped supporting because of laws so I can NEVER retune without permanently removing most of my mods. I am NOT going to put up with getting pulled over constantly. I hate to sell a 413whp WRX I just bought but I have no desire to practice up on my sidewalk Olympics and be on a first name basis with local police.

[@WRXGarage]

The quietest option is the stock exhaust! You should be able to buy a 3" to 2.5" converter to use the stock catback with your jpipe.

[@JALNIN66]

@@WRXGarage Thanks so much for your quick response. I'm subscribing now. But wouldn't it require a retune if I downsize to 2.5"? I thought I had to stay with 3" to avoid a retune. If I can get away with it I'll do it. My son has a stock exhaust on his 2016 and he wants the R400 so we just could swap. It is not possible for me to ever retune this car because my mods are no longer supported by COBB.

[@WRXGarage]

The catback section really doesn't effect much at all to be honest. I'd be very very surprised if it effects your tune or power output! The COBB jpipe is designed to hookup directly to a stock catback

[@BL4CKSTEEL]

so this set up passes emissions?

[@WRXGarage]

Depends on your state, but it is a catted jpipe and should pass most places.

[@thisjustanother]

@@krstudio6391 the r400 wasnt meant to be the loudest, but i believe it sounds the best out of any of the other choices. im pretty much full bolt on. nearing 380 Whp and 350 torque. but i do believe the catted J pipe does help increase the sound level of the car. i have no regrets with the combo

[@300zxdriver]

Does the cat back really make any horsepower difference?

[@WRXGarage]

Nope. Maybe 5-10hp when you have the stock jpipe.

[@Smljhndnsmr]

I'm about to install that same GrimmSpeed J-pipe on my 2021 WRX, but my plan is to pair it with Cobb's SS catback. While running Cobb's stage 2 OTS map with GrimmSpeed's J-pipe, did you encounter any concerning number trends with AF Learning, AF Correction, DAM, Feedback Knock, Fine Knock Learn, etc? I'm mainly asking because I'd like to run Cobb's stage 2+ OTS map for a while rather than immediately springing for a dyno tune upon J-pipe installation. How long did you run Cobb's stage 2 OTS map before moving on to an E-tune or dyno tune? Thanks.

[@WRXGarage]

Running COBB's OTS stage 2 with the GS jpipe is absolutely safe. Maybe not 100% optimized.. an etune will likely be more reliable and stronger overall. That being said, I ran the stage 2 COBB tune for around 6-8 months and didn't have any issues. If you have access to 93 octane, I'd run 93 octane with the 91 tune.

[@Smljhndnsmr]

@@WRXGarage I only have access to 91 octane. Also, I forgot to ask about codes. Since the location of the catalytic converter is different on GrimmSpeed's J-pipe as compared to Cobb's J-pipes, will that cause O2 sensor codes to occur?

[@WRXGarage]

No codes on my end!

[@Dillz107]

Thanks for the video. Your the only one I saw on KZbin that did the heat wrap. I live in Ny , and am worried that the snow/salt combo could cause damage to the pipe if I put this on. Is this true? What made you decide to do this? I purchased the jpipe but didn’t install it yet. Want to do the wrap before I attempt to install I am also worried about stripping the bolts.

[@WRXGarage]

As the heat wrap heats up, it hardens, kind of creating a bit of a barrier. In my opinion, it will atleast keep the salt off the pipe itself. As long as you drive frequently, the heat being put into the wrap will keep it dry! I decided to add the wrap to help reduce heatsoak near the turbo! It actually helps with getting the Cat hotter faster as well. As for stripping the studs... It's a gamble, some people have no issues, many strip or break atleast one. Definitely pre-soak them in PBblaster overnight if possible, also heat the turbo housing with a torch if possible when actually removing them

[@necromancer___3054]

There’s a cat in there? It looks like a straight pipe lol

[@WRXGarage]

I don't think grimmspeed even makes a catless version anymore tbh. Yes, there's a high-cell cat in there

[@MythicLady]

On a scale of 1 (stock) - 10 (Tomei), how loud would you rate this set up?

1 being stock, 10 being a catless jpipe with tomei catback.. this would be a 7.

[@mattcantsee3929]

Have you heard this in comparison to the Tomei catback? Paired with the catted grimspeed. Interested to know if its louder. Have a stp right now and wanted louder lol

The tomei is basically a straight pipe so yes it would be much much louder. In my opinion, single exits are way too raspy and Honda-ish on the FA engine. I would definitely look into the ets extreme with a resonated midpipe.

Is this is CT?

[@joshhach389]

sorry to sound ricey, but does it pop?

[@WRXGarage]

Yes.. it pops a ton on downshifts and revs. It also pops really hard on upshifts if you're driving aggressively. Doesn't have a burble tune either

[@balance667]

No restriction would be catless lol

[@WRXGarage]

For a full bolt-on Subaru, a catless downpipe wouldn't add more horsepower vs a catted one.. at that point the car would have external wastegates anyways, so there's not really any real reason to go catless over catted unless you just want to be louder and hear a bit more turbo spool!

[@carlosf8451]

How many ft was the wrap you used for your GS J-pipe? Im planning on doing the same but with black but i want to cover the whole J-Pipe.

[@WRXGarage]

I bought 50 ft and probably used about 20ft! As you can see we only went down past the trans with it. You'd probably be able to wrap the entire pipe up to the cat with 50. I wouldn't recommend wrapping over the cat tho. That thing operates at 1200-1500 F so you don't want that over heating and destroying itself.

[@carlosf8451]

@@WRXGarage Thanks. Is there any recommended silicone high heat spray for this instead of the wrap? If so which is better. I got the same J-Pipe

[@WRXGarage]

I personally wouldn't recommend silicone unless you're sealing some of the flanges

How’s it sound on the highway? Any drone?

Not much drone at all compared to other setups!

@@WRXGarage thanks for quick response. I’m debating between this and Cobb’s resonated j pipe. I currently have a nameless axle back with 5” mufflers. I’m just worried this will make it too loud, thoughts?

[@caltamirano83ify]

Does the Cobb stage 2 map work with this? or do you need a tune?

[@WRXGarage]

It works fine. Probably not the best in the long term though, because the Cobb stage 2 tune is made for the Cobb jpipe.

[@caltamirano83ify]

@@WRXGarage i've been buying parts to install them and pay for a tune once instead of every single time after installing something new... knowing that it works i'm going to install the j pipe over the weekend... so you haven't had any issues driving it hard?

[@WRXGarage]

I got an etune and then a protune after this! Go watch those videos and you can see what I did in what order. Definitely reach out to your tuner and ask if they can send you a temporary tune to flash so you can install all the parts and drive to them.

Not 2+, just 2. And yes it's ok as a temporary solution.

Did you have the CEL on? I have the same set up and I have the Cobb accessport tube stage 2, but I have the Check engine light

No CEL for me! Are you running a catless jpipe? Also, did you delete one of the restrictor pills?

What OTS tune are you running? High or low wastegate? Stage 2 or 2+? 91 or 93?

This is the same setup I'm saving up for. Currently just have the r400. Thanks for the video. I would be hesitant to run this without a pro tune though

[@WRXGarage]

The Cobb stage 2 is doing well so far! But yes, an etune or a protune from a reputable source is always better than ots

@bellaBc did you end up doing this setup? I’m worried it will be too loud.

[@bellabc]

@@davidswallow3924 not yet, but I drove in someone's car with this setup and yeah it's significantly louder.

@@bellabc that’s too bad. I’m ready to go stage 2, but don’t want the car any louder. It’s right at the sweet spot with the intake and R400,cat-back.

You could always trade the r400 for a Q300! q300 + jpipe is about as loud as just a r400 catback, if not softer

@@WRXGarage make sure to get an intake with an airbox, really important for these cars, anything else would perform worse than the stock intake. I went with Cobb and I'm really happy with it.
