Love it install was easy will definitely be buying the catted j pipe and fmic when I get a pro tune scheduled
The best exhaust you can get for the sti. For sure! Worth every penny.
If you want a loud ass exhaust and can deal with all the drone from no resonators/mufflers then this is the one for you, you can hear the hell out of the turbo and that’s exactly what I wanted. Up to par with Tomei as far as loudness. Install was ridiculously easy
I love this exhaust a lot and gives little pops. It’s loud but a good loud amazing quality and sound I would recommend this to anyone with an sti or any car one down side is if you have coils or bags you’ll have to raise your car just a tad because I have coils and I’ve flush with my fenders but the exhaust and the “Y” bend sits very low so you hit man hole covers or really anything. Can’t find a way to get past it but to get bigger side wall tires and raise it a little bit other then that easy instal all around a Greta product (email me if you have an sti and you found a way to raise your exhaust up at the “Y” bend so it doesn’t scrap) it would be much appreciated.
This kit is great!! Went together easy and sounds beyond amazing!! I get lots and lots of comments
The ETS Cat-back exhaust for the 2015-2018 WRX is a made right here in our facility. This exhaust features a true 3.0 all the way through mid-pipe that connects to the rear section splitting into two 3" pipes and finished off with quad 3.5" tips. We use V-band connections on all connections (except the factory 2 bolt) for a leak proof seal (no gaskets to blow out or replace!).
- True 3.0" All The Way From Mating Flange To Muffler Tips (adapter included to fit stock downpipe if needed)
- V-Band Connections For a Leak Proof Seal
- Quad 3.5" Double Wall SS Tips
- 41lbs (10lbs €“ midpipe, 7lbs €“ y-pipe, 24lbs axle back)
*** Please note the blue tips will fade over time. This is common on all blue tipped exhaust systems.
QUESTIONS & ANSWERSAsk a Question
What's the weight of the cat back kit with the resonator? Thanks.
The weight of this exhaust system boxed and shipped is 56lbs.
Do I need anything else like flanges or gaskets bolts anything at all. Does the kit comes with everything?
This will include everything needed for install. That includes the adapter to work with stock exhaust. The only thing reused from the old exhaust is the stock gasket if you are running a stock downpipe.
Is it recommended to buy a new donut gasket for this install?
No, you throw the stock donut gasket away.
Is everything included in the kit to connect to a stock down pipe or do I need any additional adapters or gaskets?
Everything needed for stock downpipe and aftermarket downpipe is now included.
Does this fit on 2019 wrx?
The catback does fit all 15+ WRXs.
I have your ets extreme with res on my 16 sti and was looking to get the next one down? Just the tips tho? With mufflers. Was wonder what my options are
If you want to add mufflers to your current catback this is what you will need
Hey, do you guys offer sponsorships or military discounts?
Here is a link to our military discount - https://www.extremeturbosystems.com/pages/ets-military-discount
Does the ETS mid/y-pipe connect directly to the factory down pipe or do I need adapters?
Yes, we designed our catback to be a factory replacement. You will need 3" gasket.
What is the size of the exhaust tip? 3 or 3.5?
3.5" Quad tips!
Will I get a HP gain? If so, how much?
You will see a power gain when matched with a quality tune. How much is really dependent on the tune.
With this mate with the Cobb downpipe?
Yes it will
Will this ETS CATBACK work with the INVIDIA CATLESS DOWNPIPE?
Yes, it will
I was wondering if the ETS SUBARU WRX/STI 2015+ CATBACK EXHAUST SYSTEM fit a 2019
The catbacks do fit the 19+
Will this fit the 2020 STI as well?
We haven't had confirmed fitment on the 2020 yet but it should as I don't think they made any significan't changes to the bumper or chassis.
Is there anyways to just purchase the axle back muffler portion? I have an ets y and mid pipe and looking to get the mufflers
Yes we list the rear section of the catback in the exhaust section of our website.
one of my clamps fell off of my WRX 2018, is there a way I could get a replacement?
Yes, we have the T-Bolt clamps available separate on our website.
Is this legal for street use? What’s the current decimal levels?
This is for offroad use. There are a lot of variants that dictate volume
Which combination do you recommend to avoid drone? Car is a 2019 STI and sees a lot of road trips.
Resonators and mufflers are a must then!
Will the full exhaust system fit the 2019 Subaru wrx sti , and if so will it need a tune ?
The catback will bolt straight up. No tune needed if the cat remains in place.
Do you guys offer military discount? If so how do i go about getting it on my order
I'm considering both your j-pipe and catback exhaust for my 2017 WRX. Have you considered offering both as a turbo back system with the 2-bolt flange replaced with a v-band? With all the other connections being v-bands, it would be great to eliminate that last bolted/gasketed connection.
We use the 2-bolt to make sure our Jpipe can pair with a stock catback, and our catback can pair with a stock Jpipe. If you purchase both of those parts it would be considered a "turbo back system.
Do i need a separate adapter to bolt this cat back on to my stock Sti downpipe?
https://www.extremeturbosystems.com/collections/15-19-sti-exhaust-systems/products/grimmspeed-subaru-downpipe-to-3in-catback-adapter This is what you are looking for.
Do the tips only come double wall? Really wanna run a full ETS J-Pipe to Catback/Turboback, but don’t like double walled tips.
We only do the double wall on the Subaru exhausts.
Compatible with 2019 sti ?
Yes, the catback is.
Will this exhaust require a tune? Can I run it with no issues after install?
No tune required if the factory catalytic converter remains in place. To really benefit from it, we do suggest getting the tune.
is the exhaust full titanium and how much will the hp increase?
The exhaust is Stainless Steel.
I have a ETS full cat-back on my 2017 wrx with mufflers and I am looking to see if I can buy just the axel-back portion to get rid of the mufflers. Is that something I can do or do I have to buy the full new cat-back?
Sounds great but will this increase my hp? I currently have stock exhaust.
Absolutely, anytime you can free up exhaust flow in a turbo car you are going to have better spool and be able to make power easier.
What is the difference in the ETS Catback Extreme with resonator and without? Which is more loud?
Volume difference will be minimal, though the resonated is likely quieter. The resonator really just helps to reduce freeway droning.
