  1. an adult exhaust system

    By C.A.O. May 6, 2023

    well made, fits perfect. sounds great. slightly louder than stock, but more refined sounding than many of the other cat backs. nice little growl, no drone.

  2. Awesome sound and great quality

    By Alonzo March 12, 2023

    Borla is an awesome company. I love their products. If they made a J-pipe I would buy it in heartbeat. This exhaust sounds amazing. I've hade it on for about 6-8 months now. I'm currently stage one and going stage two soon and will keep the borla because it just sounds so good. Best of all no headaches at all!

  3. Exhaust

    By Danny December 20, 2022

    I love it great fitment and very loud

  4. Great!

    By Alonzo August 29, 2022

    This is honestly a really great fit for anyone looking to get something louder than stock. but soft enough for no drone in the back. It has an amazing sound to it. This will definitely catch people attention. Great product! Installation process was very simple just make sure to WD40 all of the bolts before and it will be a fun installation and very much worth every penny!

  5. Great Choice for WRX Daily

    By Joel May 23, 2022

    This exhaust hits the nail on the head for a daily driver. Gives you way better sound than factory exhaust under throttle yet has virtually no drone at highway speeds (even with the windows up and radio off). Highly recommended if you want something more aggressive but also won't give you a headache.

  6. Absolutely amazing

    By Boston March 26, 2021

    First of all I want to say that I’ve never left a review on anything and I want to follow up with subiespeed has yet to disappoint. With that said...the only regret I have it not doing this sooner. It changed the entire driving experience of the car. It was easy to install and the fit and finish was amazing. Subiespeed got me the package super quick and I’m obsessed with driving my car all over again.

  7. Best exhaust!

    By Jinx September 6, 2020

    Subispeed came through and shipping was SUPER fast. installed the exhaust the next day and oh. My. Gawd! The car is beyond 10x better with this exhaust. Videos made it sound raspy to me, bu in person it sounds like a v8. Dont hesistate. Pull the trigger. No drone. You primarily hear it when accelerating but once cruising it shuts up. Thanks again Subispeed!

  8. Smiles all around

    By Aubrey August 17, 2020

    The Borla sounds amazing. I had a Borla on my old miata which made me kind of know this was what I wanted for the WRX. I looked around at video reviews, sound clips and so on for many different cat backs, but this one still sounded the best. And man it is good. I wish it was a little bit louder, but Ive also noticed that the 2015+ WRX is "quiet" even with no exhaust on. The cold start with this Borla sounds evil, in such a good way. At warm idle, it sounds no different really than stock. But when you but the foot down holy crap. It gets loud, the turbo is more apparent, and overall my smile doest have enough room on my face. Highly recommend this for anyone who wants to have a smile and appreciates rumbles and poppy noises. If you just want pure loud and nothing else, this may not be what you want. I love it though!

  9. WOW

    By Manny August 7, 2019

    There are many exhaust out there, but this is the one. This was my first performance modification on my 2018 STI and wished I would have done it sooner, deep aggressive tone when you want it, no drone and quiet at highway speed on cruise control. Cold Starts sound amazing and I have noticed smoother run through the RPM's, especially past 5.5K.

  10. Best STI Catback

    By Dalton July 30, 2019

    After months of searching and listening to sounds clips on YouTube, I finally decided on the Borla S-type for my 2017 STI. The fitment was perfect, mated right up to the stock downpipe and fit nicely on both sides of the bumper. The sound, the sound is INCREDIBLE. I have never heard a muffled catback that sounds so aggressive under throttle. It is LOUD! But even after 2 years cruising on the high at any speed produces zero drone whatsoever. I would highly recommend this catback. Listen to some sound clips on YouTube compared to other systems and decide for yourself!

  11. Money well spent!

    By Eric January 16, 2018

    I would rate satisfaction at 10 if i could, absolutely love this cat back system! Deep, aggressive tone all the time, but just subtle enough to not attract too much attention. My WRX roars when i put my foot down, it puts a smile on my face every time i drive. I would highly recommend this to a friend.

  12. Wonderful

    By Joseph May 10, 2017

    Had this catback exhaust installed professional, required some welding to get the tips in the right spots without touching the bumpers. Aside from that, it sound wonderful. The interior cabin sound is very similar to the stock system, which if you pay attention to is actually quite loud and does tend to drone by itself. However this exhaust changes that it makes it sound closer to a rally car in all honesty. It sounds beyond wonderful, minimal drone if any at all, not really loud, but when you give it gas you remember you have an exhaust. The car should have come from the factory like this. Do yourself a favor, buy it and you won't regret it.

  13. Awesome

    By Mike April 5, 2017

    This exhaust rocks. Absolutely zero drone in the cabin. Nice low growl at idle, and sounds great past 4k rpm. It came packaged really well, and took about an hour to install with out a lift. If you are looking for an exhaust that will not draw too much attention to cops, but are looking to take that next step in mods for your car. This is the one.
