2007-2012 SX4 Exhaust

This SX4 Muffler is the muffler of choice by Road Race Motorsports. We’ve used this virtually on all of our concept cars and both turbo and N/A platforms. It is a very unique muffler and the architecture of the muffler is such that it makes more horsepower over the oval design while maintaining a deep and sporty tone. This is perfect to create your own cat-back or axle-back system. This setup has been proven to make horsepower from a wide range of our vehicles we specialize in such as Fiat, Jeep's, and Mitsubishi’s.

Note that this unit will need to be custom installed by a muffler shop, however this will be your best solution for the SX4 whether you are AWD or FWD.
