refreshingly LOUD
pwndotcom 1 year ago
when i purchased this exhaust, i was worried it would be super loud, especially since i live in the SF bay area (cops here rule with an iron fist). after install, i must say... IT'S LOUD, but in a good way. note, this exhaust isn't for everyone, but if you like loud cars, with a deep rumbling noise, this is for you. after driving around in it for 2 months, i am even thinking of getting the RACE version pipe to get ride of the resonator. you definitely get used to the noise + my neighbors haven't complained.

I absolutely love this exhaust. I have it paired with the Invidia catless downpipe and it sounds amazing. Tuned on Cobb Stage 2 map, it has a great, deep tone, and best of all there is no rasp. Great throttle response and quickness to it. I fell in love with my car all over again. Great Product and great customer service and fast shipping from RSD!

Awesome Exhaust! rumble is more distinct.

The install was pretty straight forward with the help of a friend. Exhaust note is amazing!!! it brings out that distinct subi/boxer rumble. The only drawbacks of this catback is if you plan on installing it to your stock downpipe, be prepared for an exhaust leak. Its a small leak, but still very bothersome as I know I have the leak. Not to worry though, you can always purchase the grimmspeed oem downpipe to 3inch cbe adapter if you have OCD like me. Haha. I havent purchased it yet, but will soon. Overall you guys will be very satisfied with the exhaust... Nothing bad about it expect the leak.

The exhaust fits great on my car. It sat close to my sway bar and rattled, so I had to order longer hangers. But no problem with it, defiantly worth it to buy. It sounds amazing

Great Sound
FrankF 2 years ago
Great sound with My AMR EL header and Catless downpipe. No drone with my set up. If the sound is too loud I put the silencer in and it does significantly lower the sound to almost stock levels. I can imagine this exhaust being a little annoying(drone) with the UEL header design.


  • AnswerQ: current exhaust compatibility/ bumper compatibility  jake 30 days ago

    I have a '14 impreza wrx sedan with the stock upgrade SPT exhaust setup currently, could i use the SPT downpipe ( if the SPT system comes with one, idk if it does haha) without having to change anything and would this exhaust fit with the stock bumper?

    • A: The SPT system is just a catback, so no need to worry about the downpipe! While a downpipe adapter is not required, it is highly recommended. Running a downpipe adapter in addition to an OEM Donut Gasket will prevent major exhaust leaks from occurring. This exhaust should fit just fine with your stock bumper.

  • AnswerQ: race/street  spynldoc31719 2 months ago

    I was wondering if this was the race or street version.

    • A: The midpipe in this setup is resonated making it the standard N1 setup.

  • AnswerQ: Weight  TheSilentRose 6 months ago

    Compared to the tomei exhaust, is this one fairly light weight as well?

    • A: The Tomei will be around 25lbs, and this Invidia exhaust weighs around 40.00lbs.

  • AnswerQ: Piping size  Brockcolelee47698 7 months ago

    Is the whole piping size 3 or does it taper to 2.5 at the midpipe to downpipe connection?

    • A: This is 3in throughout the entire pipe.

  • AnswerQ: 2015 STI fitment  rspawlik87459 9 months ago

    I'm interested in the N1 single tip for my 2015 STI. Fitment is not confirmed. What kind of modifications are needed to fit?

    • A: 2008-2014 cat backs generally do not fit 2015 models because the extra chassis bracing on 2015 models interferes with the exhaust.
