Features & Product Details

Mishimoto has decided to expand their line of exhaust parts. So with that out of the way, here is a win-win situation. Not only do you get a quality stainless steel product that performs amazing, but you also get that mind blowing lifetime warranty from Mishimoto.

Right here is the 2015+ Subaru WRX/STI cat-back exhaust. With one of the biggest complaints from WRX owners is that it lacks an aggressive tone. By installing this, you not only do you gain that tone, but you allow the system to breather easier giving you some extra power. The Mishimoto cat back exhaust provides an extremely aggressive turbo and exhaust tone under acceleration and boost, giving you that sweet tone you've been looking for!

Very well made 11 months ago

The exhaust came quick and very well packaged. Took 30mins- 1 hour to install very easy and no issues with fitment. With stock downpipe make sure to get the 3 inch adapter so no gas leak. Noise wise it is quiet still but has a small rumble compared to the stock and can hear the car when idling unlike the stock exhaust. Over all was a great choice

It's ok I was hoping for a 3' all the way. When it came on the Y pipe it's only 2' 1/2 so yea.

Stock 2015 Subaru WRX STi - Mishimoto Catback Exhaust System 3 years ago
WRX Curve
I see a lot of people asking for videos of STOCK STi's with the exhaust, but the major outlets are only posting videos with other parts as well, such as downpipes and intakes. These significantly change the sound. I decided to make this video after installing it pipe (to my neighbor's delight). I have no other aftermarket parts on my car; this is the first. I love the deep sound this exhaust provides; this video doesn't do it justice. My STi now sounds as powerful as it feels. While the performance benefits of this system are minimal (3-4 HP gains), the sound is exactly what I was looking for. Loud and throaty!

QUESTIONS & ANSWERS

  • Q: 2015 STI Stock downpipe   James_boehme923 years ago

    Any way to get a video review on the mishimoto catback on a stock STI and info about the amount of drone it has? Thank you!

      A:  Unfortunately, we do not have any videos of the exhaust on a stock setup, as our shop STI has an extensive amount of upgrades. Most aftermarket exhausts will have some drone, due to the reduced restriction of the exhaust.
