The muffler inside contains continuous piping design and use of Advantex material that results in an excellent free-flow exhaust with optimized back pressure, giving greater horsepower, torque gains and a rich deep sporty sound.

Q300 for Civic Si

By Joe on 1/27/2013

This exhaust is great! Fit absolutely perfect with no problems. Has a nice deep aggressive tone..and not annoying loud. It is my wife's car..and she hates a loud exhaust. She likes this one..so I did good. Lol. Thanks to Club RSX/K-Series Parts!
