  1. If you're looking for a quiet cat-back system this is it!

    By Aaron July 17, 2019

    Just installed on my 2018 STI, everything needed for the install was included, exhaust looks, and fits great. Install was very easy, only took me about 20 min. Overall the exhaust is quiet as stock at idle, with the sound level picking up to about 10 DB louder around 1200 rpm and maintains that slightly louder tone throughout the rev range.

  2. Great System!!

    I love this exhaust! With stock cat its actually quieter then stock at Idle it does get "louder" and sound amazing when you floor it!
