Why You Should NOT Go Stage 2+ On Your 2015+ STI

[@1lesavage]

If you run a downpipe without a tune on a subaru you deserve to have your engine go kaboom 😂

[@L.rt12]

[@zacharyweidenhammer8104]

100% agreed . People who even think about doing that deserve it the full affect

[@footballfan7894]

You can drive it without a tune its not restrictive like the original downpipe thats restrictive with two cats . Its getting all the gasses out , but I heard a tune is advised to get the most out of it. Plus to stop the check engine light if it happens . I think more so you need a tune for the catless.

[@ridetoliveofficial693]

if you change any air flow whether it is intake or exhaust (excluding putting a cat back/axle back exhaust) you most definitely should tune for it. If you don't you are playing with fire and if that fire happens to be your daily you're gonna have a bad time.

[@footballfan7894]

@@ridetoliveofficial693 yeah I think you do need a tune lol. I was on the fence about it in my previous comments. But yes a tune is very necessary for this upgrade. If you stay off of boost you can drive it for awhile but who the fuck stays off of any boost nowadays.

[@kiritowow2736]

when you mod the STI, this always happen: 1. Just do an axel back, I just want more boxer rumber. 2 lets do a catback, axel back is not that aggressive 3 Boxer rumble is not enough, I need some noise from engine bay!!let a cold air intake and a BOV, and TUNE It!(so I buy access port, BOV and intake, spend money on protune simultaneously) 4 The sound is still not AGGRESSIVE, I need more sound from the exaust, lets do a catless downpipe!!!! 5 I need to upgrade the fuel system to keep up the power 6 I need to upgrade the turbo to make the car not run that hard 7 I need to upgrade TMIC to a FMIC 8 OH, my STI already got 400 whp, I think it is time to change the internal to make it run safely, lets do a forged piston!!! ....... 10 EJ257 KABOOOOM....

[@Devon_Meadows]

Dont blow if you can drive and have a good tune. Im “stage 1.5” on my 18 STI. The injectors are low CC on these cars, but its the fuel pump more than it is the injectors. You can make 320-330 all day on stock injectors with upgraded FP. I have a cobb DP to cat back exhaust. No intake, I make 312 whp, 363 tq (high map) and 307/350 (on low map) and highest IDC that I hit on track is 90-91%. I drive it daily and to and from the track. Max 86% on road if i do a hard pull. Im on Long Island as well. My car runs incredibly

[@Suisam1]

@drliu in 99% of cases people don't understand how bad it is for an engine to have injectors go over 80% duty. Any modification has the potential to exceed stock injectors easily on a Subaru. If you're going to spend $$$ on upgrades....spend a little more $$$ on oversized injectors so your tune can be safe and have the ability for the ECU to adapt if extra fuel is required and beleive me, while tuning them I've seen people try to run cars that try to request +115% injector duty and that is impossible when they thought they had that kind of head room. ALl it takes is season changes and other scenarios. Spend the extra to get the correct supporting mods and be safe!!! Think about it....injectors are cheaper than buying a brand new short block....

[@Lucas-nz8em]

I’ve ran multiple stage 2 Subarus on reputable e tunes at over 100% IDC well over 100k with zero problems

[@octurbojoe]

By the time you hit stage 3, the turbo will be next thing that gets maxed out. Upgrade to an 18-20G size turbo to make the same power with less effort than an overworked, tiny, stock turbo. Go too big in turbo size and too high in power, you'll lose response while eventually maxing out your engine's structural integrity. Also, the stock TMIC, radiator, and oil cooler were designed for stock horsepower. They need to be upgraded as you increase horsepower since more heat is generated to make the car accelerate faster. If you go FMIC, add rear facing hood vents or replace the hood for a rear vented option to dissipate the heat in the engine bay. Hood scoops with no intercoller behind it will create positive pressures in the engine compartment and will render your front heat exchangers useless, even if you have the fattest radiator installed. You're right though. The issues are mainly the owners themselves. Great video!

In the end, the only way to make 400+ wheel hp in a 2015+ wrx/ sti with no worries is to spend the $4k for a built motor with forged internals. People dont realize that stock engines are generally garbage, but they want to race those shitty mustang anyway

[@Autofreakgarage]

[@svtwrc]

Excellent info ! Another way to protect the motor is use a really top tier fuel 93 octane but tune the car for 91 octane. The extra octane level helps with knock. If you tuned for 93 and you get questionable fuel or it’s from the bottom of the stations tank it may not actually be 91 half by the time it’s pumped. Loving this channel.

[@seanharreld1104]

[@justinmielsch5924]

What size injectors

[@Chinnysmylr]

I completely agree. This car gets bad rep due to incomplete work and not doing it properly. Tuning is a must if you do a downpipes and anything else with the engine. If you take care of your car, pay attention on how it is driving and not push it beyond its limits in accordance with your mods, it will last you longer and give you smiles for a long time. I think majority time people rush and drive it unsafely, or too aggressively without proper mods running and that is why we hear stories of them breaking down. I have run a cvt 2019 with 274 whP and it was great. I didn't push it beyond its limits , listened to my tuner and what professional advise they had to offer. It lasted me a great run.

If you look at dyno comparisons the WRX actually gets bigger gains than the sti until you go full bolt on plus fuel upgrades (stage 3+) so that's what I jumped to.

[@DWR6]

I purchased a used 2019 STI which has a catted Invidia downpipe and COBB SF intake. I am starting to understand why I am getting P0420 codes now. Can I get an OEM downpipe and downgrade to Stage 1? If so, does it have to be an OEM downpipe or is there an aftermarket equivalent? The other option is to move to Stage 3, I guess. I prefer reliability over power seeking. What do you suggest?

[@bradgreen987]

If you take your car to a tuner, put it on a dyno, all issues can be tuned out. People that run e tunes blow their cars up. I've got a heavily modified 2016 wrx and it screams, daily driver at 320 wheel hp. Just don't exceed 350 torque! That's the key

If you are doing both an intake and down pipe, you’ll need to upgrade the fuel system. Downpipes open up the flow of the exhaust and gives a nice boost in power. There’s no set number of gains from just a downpipe and each car will yield different results.

NOT STAGE 2+!!! I currently have a MAP Intake, Accessport (Stage 1+ basically) Just by adding the Downpipe will put me at Stage 2, right?? And will it be SAFE after a good Etune??? 🤔

[@Autofreakgarage]

Stage 2+ is a tune, Downpipe and intake. I’d recommend upgrading the fuel system if you go this route. So if you already have an intake and you add a downpipe, you’ll be at stage 2+ and need to start upgrading other areas to run it safely.

[@Juanparrastudio]

@@Autofreakgarage damn man you are awesome thanks for answering! So… Going JUST STAGE 2, would be just a tune an a Down-pipe BUT with a STOCK intake???

[@Specter57]

Car's looking good there, nice job. Completely agree with the video. Do you plan on doing any chassis mods?

[@Autofreakgarage]

I’ve done coils, sways, endlinks, lca’s, and strut bar. Have one more piece coming, but that’s about it. It’s a daily so I don’t want to go overboard and make it unbearable to drive.

[@freemaysin5088]

Is it safe to just do a good intake and full system exhaust ,then run a tune to adjust accordingly and just keep everything "stock"? I'm about to try to get one of these ,and all I truly want is a full system borla and a cold air intake and let the car live its life that way. Think thats a safe move?

[@Autofreakgarage]

No, I would not recommend running an intake and a full turboback alone. A proper tune and all the supporting fueling mods are a must if you want it to run smoothly, safely, and properly.

[@freemaysin5088]

@@Autofreakgarage I think you misread, I 100% know i need a tune along with the intake & exhaust what i mean is i dont wanna start modifying fuel system, cooling/oil flow systems i really just wanna get a nice intake, borla exhaust and a tune to bring it up to speed and then just keep the car at that point. Sorry hopefully I don't come off as rude i've just been following your channel for a while and you seem very knowledgeable. Alot of the company's i talk to seem like they are trying to rush me into spending as much money on parts and get to stage 3 asap and I just know how these cars are. I wanna get mine unlocked how it should be but i dont wanna push limits, i've seen these cars never see 50k miles and i've also seen some with over 300k

[@Autofreakgarage]

I did not misread it. I was explaining that if you want to do a downpipe and an intake on the VA (15+) STI, it is 100% recommended to upgraded all the fueling components. At stage 1+ (tune and intake), your stock injectors are maxed out. Going with a downpipe will open up more power (and will need more fuel) and since the injectors won't be able to keep up, it'll cause your motor to lean out and cause premature wear and it will have a high probability of grenading itself. Companies are not trying to make you spend money. They are giving you advise on how to properly modify your 2015+ EJ25 motor and have it run smoothly, safely, and properly. The wrx and sti's that you see have 300K miles are the ones that modified correctly and maintain their cars religiously. Which are two things I ALWAYS preach.

Wow all I gotta say is “so well said” !!! I have a 2014 sti hatch with close to the same mods as you with Cobb sf and I’m happy to drive a reliable subaru that is super fun and doesn’t blow up lol. I’ve had a lot of Subarus a 98RS with a 02 wrx swap by rallispec in New Jersey super happy drove the car regularly never had a problem they are a great shop!!! and a bunch of other Subaru’s, Wrx 02 bugeye, as well as Outback’s and never really had any issues. I totally agree that a lot of the issues are user error for sure. At my last job for eight years delivering new cars to journalists all over the north east, I drove practically every car under the sun from the Dodge Hellcat Redeye and Track Hawk(straight line cars, no fun lol) all the Gtis Golf Rs, Nissan Zs and GTRs, BMW M cars, all the Mercedes AMG cars all the Audi RS cars Audi R8s(personal favorite) Porsche 911 Turbos, Bentley GTs, Rolls Royces, Lamborghini Aventador‘s and many more (best job I ever had lol), and I have to say that my Sti still felt the best as a daily driving fun car on New York, New Jersey and Pennsylvania roads. Great video man!!!

[@patryx2058]

I only want the intake but don’t want to run the ots map. What tune are you running ? And for how many mikes ? Thanks

[@ChazzyMcD]

Is it different for the VA wrx, I was looking at Grimmspeed stage 3 kit and it does not include fueling upgrades.

[@ChazzyMcD]

I know it’s direct injection, does it get fuel more efficiently or would you suggest fueling upgrades for the wrx as well, for stage 2, or 3.

Love your channel, I have a 2016 STi stage 1+ MAPerformance intake and OTS tune. I’m really considering going your route and swapping for a Cobb sf intake, then Brentuning e tune. My question is, did you feel a noticeable power increase with the e tune over the MAPerformance stage 1+ OTS tune? Thanks man, your videos are super helpful!

[@Autofreakgarage]

Thanks for the support! I felt a difference, yes. But not necessarily an increase. The map tune felt more aggressive and twitchy, where the bren feels way smoother, in control and dialed. It’s not always about power! I highly recommend getting off the map and going to bren. You’ll be way happier and so will the car.

[@ZachThreeve]

Great to know, the MAP tune has been good to me but I live in CA and this intake is not CARB approved, also I worry about water during heavy rain. I’m still within MAPs warranty period and can return my intake and buy Cobb’s intake. Thank you for the info and for your honest feedback!
