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
- 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
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?

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.
