    Borla S-Type Cat Back Exhaust ( Part Number: 140595)
    ***** 5 stars  4 months ago

    Local muffler shop said it was the best fitting Borla system they’ve ever installed. Sounds amazing. Loud at cold start, has a nice low growl at idle and roars when you step on the throttle with some pops and crackles in there. Definitely makes heads turn. My kids love it and ask me to go fast all the time bc they like to hear the exhaust. I can tell it adds a little horsepower from stock. No drone in the cabin. Normal cruising with radio on you can barely hear it.

    Sounds lovely but a bit too quiet. Borla did a great job on eliminating droning. The pops are so quiet that they're only barely noticeable. Overall I like it, just wish it was a bit louder especially the pops.

    Sounds great, fit like a glove and I have zero regrets. It is loud at cold start but quiets down once the car warms up, sounds pretty badass.

    I got my 2017 WRX a couple of months ago and of course, the first thing I wanted to do was put on a new exhaust. I originally put on a set of Invidia Gemini R400 Single Layer Cat-Back Exhaust w/Titanium tips. It was super loud (good) BUT it was also very dronie (bad). The whole cabin vibrated at cruising speed. I switched to the Borla and have been very happy with them. Not much louder than stock, but very pleasing to the ear. They have a really deep sound and a nice rumble on the deceleration.

    • Q: 2021 STI?  IAN H1 year ago

      This should fit the 2021 sti, correct?
    • Q: Gaskets  gmira132 years ago

      I have a Cobb 3" downpipe. Will I need to replace the doughnut gasket? Or do I even need it since both are 3" ?
    • Q: Borla #140595  STIlimited20202 years ago

      What else do I need to install this exhaust ? Do I need gasket if yes can you give me part number ?
    • Q: Stock 2020 STI  yonnie517092 years ago

      I just purchased a 2020 STI. Do I need anything other then a new donut gasket to install this axle back?
    • Q: Fit  HonestAbe10313 years ago

      Is this cat back straight up bolt-on, or does it need an adapter for a stock 2019 WRX? Does it need any cutting of the pipe? I watched a video of someone that said they needed to cut the y pipes before the muffler in order to reduce rubbing. Thank you in advance.

        A:  Assuming you're installing it with a stock exhaust, this should bolt up without any modifications necessary.
