Invidia Q300 or R400 TURBOBACK? | BEST Exhausts for Subaru

In this episode I switch out my R400 for the Q300 mufflers. If you're asking, didn't you move AWAY from the Q300? Then you are right, I did. But then I installed a down pipe also by Invidia and now its way too loud and drones way too much. Watch this video to hear my thoughts.
Invidia Q300 vs R400 CATBACK Comparison Video: • Invidia Q300 or R400 C...
For those who are new to modifying cars, I forgot to mention that this a TURBO BACK EXHAUST includes a down/dump pipe which starts from the turbo going all the way through to the back. Turbo back exhausts or changing your down pipe WILL NEED a tune. A catback exhaust is everything AFTER the catalytic converter and WILL NOT require a tune.

I was also debating on witch one to buy and you helped me get the Q300. I’m very happy with it . 👍🏻

[@MrDuongTV1]

Cheers mate! Hope you're also enjoying the channel 🙂

[@edenconnell4322]

Great video. Have the Q300 turboback on my 2016 STI and I just love it. I have two kids so can't have too much noise and drone. At the lights it's super quiet then when I rev it people will notice. Love the sound it's addictive especially with the Process West cold air intake. Couldn't be happier with my decision.

[@MrDuongTV1]

That is a recipe for an eargasm mate. Great to hear that you're enjoying it 🤙

Finally exhaust clips without crappy audio so I can hear how good they sound. I was starting to worry a turbo back would make mine sound like a straight piped Civic😅

Thanks so much I’ve just ordered the q300 and my 2023 wrx won’t arrive till July subscribed too

Thanks for watching mate!! Really appreciate the support :) Congrats on the new car, and new exhaust!! Check out my latest episode about an STI engine and its catastrophic failure!

Oh where'd ya see me mate? 😂

[@shawnz5272]

I have the Q300 single exit on my 21 sti and it sounds and looks fantastic 👌

[@MrDuongTV1]

How did you get single exit q300 to fit? Was it fabricated?

[@picolrallyteam5821]

Are QS 300 single exits available ?

[@shawnz5272]

I got mine from import image racing. Fitment is perfect and as far as I know it's still available. I literally opened the box and installed it no fabrication required

[@picolrallyteam5821]

What the sound like ? Is it noisy on low revs I prefer deep sound on low but abit loud when u press paddle

[@gamingseeks3580]

i use borla catback with stage 1 tune on my 2020 wrx nice a settle at low rpms

[@snboostfx]

Vibrant ultra quiet resonator will remove all drone if you’re okay with getting it welded in !!

That is also an option! Thanks for watching mate

Great vid big man! Just a question re: your cosmetics - which lip kit did you go with? - the stock wrx trunk spoiler removal, how did you plug the holes? Cheers

[@MrDuongTV1]

Thanks for watching mate! Appreciate the comment. I just have an OEM style/STI style lip kit. Rear splats are HT style or sth, found a cheap pair off aliexpress. For the boot, i got lucky and found someone selling a genuine sti boot and spoiler on the market place! I have a video on how I got it and how to debadge.

[@gen3v8]

I have the Invidia turbo back q300 system on my sti 200kw rumble shack tune and supports. No drone and gets a bit roudy only when the waste gate opens. Our brz q300 drones badly @2.2k and is loud, getting louder, but its muffler packing has failed(common issue) i think. Silver tips👍 I rubbed the blue off the brz`s tips.

[@MrDuongTV1]

Yeah the q300 sounds so saucey on the sti! Such a shame to hear about the muffler on the Q300... i haven't been jn the scene long enough to hear about these problems. Thanms for watching mate!

[@gen3v8]

Known on the ft86 forum. I like the sound except for the drone only at 2200rpm

[@limbu100]

I've got R400 catback for almost a year now and sounds awwwsssommme. Planning on going for invidia turboback, COBB intake and dyno tune. Any thoughts how bad drone is going to be? bearable? its just a weeknd car sort.

[@MrDuongTV1]

Hey mate! Thanks for commenting. If it's just a weekend car then yeah you won't mind if too much at all

[@Craiggg12345]

R400 with killer b headers sounds nice but drones badly during freeway cruising but makes people look at you since I don’t have the rice rumble. Q300 is low key and makes daily driving better.

[@MrDuongTV1]

Yes R400 is so loud while q300 is so much more quiet. I may look into getting headers in the future 😅

[@sonicplayroompiano4302]

Were the crackle and pops there before you did the J pipe?

[@MrDuongTV1]

Yup, though not as loud and not as frequent. Almost non-existent on Q300 catback.

[@totapakhi32]

I have got wrx CVT 2015. I m thinking the same set up q300 with j pipe. Would it be Drone inside? Thnkx

[@MrDuongTV1]

Nope wont drone inside. Though I've heard that Jpipe on CVT is not worth. You'd get more bang for buck from just tune and catback, in that case will be an R400 catback.

[@AceKylar]

I noticed people pay more respect and attention on the road when I’m with R400, less cutting off or they would yield out of my way as I’m approaching. Of course under my normal daily condition.

[@MrDuongTV1]

Lol i agree, its definitely a lot more noticeable esp to those that like to J walk right in front of you. Thanks for watching mate! Please consider subscribing if you havent already 🙂

Is a tune requierd for rhe q300 turbo back on a bone stock 2018 WRX? Thanks.

[@MrDuongTV1]

For a catback no, for a turboback, definitely yes.

[@picolrallyteam5821]

I am debating btw a invidia qs300 dual or tomei expreme single exit am confused cause i like the looks of the invidia sound of the single exit tomei as it huge silence which shows any suggestions

[@MrDuongTV1]

Ive not heard a tomei in person on the wrx/sti, but supposedly they're stupidly loud and extremely droney. Q300 is worlds quieter than tomei

[@picolrallyteam5821]

@MrDuongTV1 ok thanks for reply How's the q300 normal causing is it totally silent or abit of rumble I don't want it too loud and too low confused haha

[@vandaline6154]

Is the turbo back r400 louder than the cat back ?

[@MrDuongTV1]

Any turboback is much louder than the same catback system 🙂

[@JokerMo1023]

How’s your car driving under this super hot summer? Mine one super jerk can’t boost to much.

[@MrDuongTV1]

Yeah its okay I guess... boost doesnt kick in very hard.

[@kangshi12]

brooo, even worse when the AC is on, jerky and no power 😂😂

[@shaneelnand9350]

What are you thoughts with mods like -R400 catback -catted downpipe -dyno tune -pw cold air intake Do you think that’s alright for a daily? Do I need to upgrade the intercooler or any mods? I don’t care about the drone. I already have the R400 and PW intake now. The invidia downpipe and tune only will cost me $1600. That’s why just opting for them two. Should I save and upgrade more?

[@MrDuongTV1]

Yeah mate that sounds great. You dont need to upgrade intercooler, but it will help your car perform over long periods of time i.e. on a track day. I reckon those mods you listed are a great place to start. Check out my latest video!

[@shaneelnand9350]

@@MrDuongTV1 what about tgv delete and 3 port boost solenoid necessary?

I hate how quiet the r400 is with a stock J pipe. Not sure Wether to chuck on muffler deletes or just keep r400 and put in a catless j pipe haha

[@isoloq2975]

My goal is to chuck a catless singlet exit on my wrx though. Good vid man :)

[@MrDuongTV1]

Yeah mate its not that loud just as catback... I've heard Q300 with a catless down pipe and it sounds very very juicey!! Much better than an R400 would I reckon. Thanks for the support, I appreciate it mate :)

[@ytdweller23]

why invidia at all? overrated & overpriced. so many other options out there same quality if not better with cheaper price and an axleback-alone availability instead of being forced to buy the whole catback.

[@MrDuongTV1]

Mate to each their own, if you aren't a fan of Invidia, that is fine. For reference, Pro Speed Racing who are the parent company of Invidia, DO SELL their R400/Q300 in AXLE back only. Plus, just going axle back is restrictive for higher power brackets.

[@ytdweller23]

@@MrDuongTV1 Not against Invidia, not at all, but i'm baffled by the exaggeration pivoting around it, that's that. Even if it is available as axleback only, it only fits its own catback. What if I have an aftermarket turboback or catback of some vendor (a 3inch midpipe, so no restriction or anything) and I decided someday to replace the axleback only? Invidia won't offer a solution. I'm now running cobb dp and nameless catback, the axleback is muffler delete and it's awesome but now I'm planning to replace it by a more subtle mufflers, guess what? I went with Remark Touring Mufflers and they straight fit to the Nameless midpie and to the OEM midpipe, that's what I call flexibility and economy.
