ETS Subaru Sti 2015 + Cat Back Exhaust Extreme rear section with a special request

I first purchased an ETS cat-back with a resonator and mufflers for my 2018 STI and It is AWESOME ! I also wanted a more louder system as well so I also purchased the ETS extreme cat-back rear section with a request to have small resonators added. (My concern was the decibel levels , because in Canada there are strict noise level laws ). ETS found the solution and the request with the added resonators was fabricated. The ETS Extreme cat-back exhaust rear section with the resonators is just what I wanted. The sound (decibel level) is in the mid between the muffled and the Extreme rear section. Words can not describe it.WOW!! IT SOUNDS TOTALLY AWESOME ! I am very very satisfied with having both options with the two rear sections . 10 stars
ETS customer service (especially Ryan) was awesome to provide the solution, 10 stars.
Seriously , the ETS cat-back exhaust systems are the best quality and best sounding as well as the best looking in appearance exhaust products that I have purchased in the last 3 decades.
I totally recommend their exhaust systems. 10 stars.

Glad to hear that the parts worked out exactly how you wanted, we're always happy to help make a vision happen!

I have a WRX rather than an STI, naturally my motor is quieter. This piece combined with the mid pipe of course is as loud as anyone would like. Not to bad to frustrate the neighbors. But loud enough to get that rumble everyone's after. The best part about this exhaust is running a burble tune. The blasts are loud as can be!

Great product. Trust in ETS.

I picked up a used resonated ETS quiet for my STI a few months back…. Was a bit too quiet for my taste. Thankfully ETS has these 3” axle-back extreme versions that I can simply just bolt onto the aftermarket 3” Y-pipe. Much deeper, loud and aggressive and was everything I was looking for. This is with a stock downpipe in mind. I like the flexibility in choosing a quieter or louder system depending on my build and/or changes in volume preference. Thank you ETS!

ETS Subaru WRX/STI 2015+ Catback Exhaust - Rear Section Only

Muffled rear section only

Sounds great! Coming from the extreme rear only! I had to get muffled version as I went rotated and catless to tone down the noise lol... ETS is extremely high quality and fit. Can’t go weing especially bein vband.

Great sound but still kinda quiet imo

It has a really nice rumble and even on the stock tune gives nice pops and burbles. But it's honestly kind of quieter than just stock mid pipe and a magnaflo axle back (which I had previously). Definitely sound 100% better but it being the "extreme" edition I though it'd sound a bit louder or at least the same



Ask a Question
  • Will this reduce drone vs the extreme non-muffled tips?

    The only difference between the muffled and non muffled setup will be overall volume, the mufflers will have little/no impact on the exhaust frequency overall.

  • Hi just curious do these come with bolts to install or are they v bands I have an ets extreme catback at the moment but I want resonated mufflers and just want to see if these would work with what I have mine are v bands all around.

    If you have an ETS catback exhaust system these tips will be a direct replacement and reuse your current vband clamps.

  • Is there any sort of warranty against defects for these?

    Yes they carry a limited manufacturers warranty

  • Hi, Are these 3" pipes and finished off with quad 3.5" tips? I already run your cat-back but regret not getting the extreme version. Thanks!

    This is exactly what you are looking for.

  • Will the catback exhaust rear section fit the stock y pipe?

    No this requires a catback exhaust systems. We have 2.5" axle-back that will fit though.

  • Hi, I’m on the market for muffler deletes I have a Cobb exhaust system and it’s a 3” all around piping. Will this muffler deletes fit? And if they do do you guys offer military discount?

    Our rear section will not fit that catback exhaust. 

    We do offer a military discount. There is a tab on the left hand side of our website with the military discount info.

  • I am wondering if this will fit my exhaust i have a 2017 STI with invidia q300 exhaust system and if i just remove the mufflers on my sti and replace these will it fit and connect to the invidia Y pipe. or do i need to swap out my Y pipe with my Stock Y pipe.

    This rear section only works with an ETS midpipe. It doesn't work with the Invidia.
