The 2016-18 Focus RS is a machine the demands attention and respect wherever it’s driven. The Injen cat-back exhaust system complements the Focus RS with impressive power, gorgeous looks, and a distinct sound that is unmatched.
Unlike the competition that uses stepped down tubing, the Injen Technology system is a full 3-inch cat-back unit that is mandrel-bent using only the best 304 stainless steel available. Another unique feature of the Injen cat-back exhaust system for the RS is that it utilizes individual resonators instead of a single traverse style muffler. Not only does this provide a unique sound, but it also helps to free up power throughout the RPM range. Injen also decided to bypass the factory exhaust valve and provides a custom exhaust valve bypass module (P/N 2002) with every Injen Focus RS exhaust system. This allows you to enjoy that rich, crisp sound of your RS whenever you want.
The rear of the Injen Technology RS cat-back system is a work of art and employs multiple slip fittings to allow an infinite amount of adjustment for a precise fit right out of the box. Dual 4-inch black chrome exhaust tips complete the exhaust and provide a finished look.
