The 2016-18 Focus RS is a machine the demands attention and respect wherever it s driven. The Injen Technology cat-back exhaust system compliments the Focus RS with impressive power, gorgeous looks, and a distinct sound that is unmatched. , , Unlike our competition that uses stepped down tubing, the Injen Technology system is a full 3 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 is utilizes individual resonators instead of a single traverse style muffler.

Not only does this provide a unique sound, but also help to free up power throughout the RPM range. Injen Technology 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 allow 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 black chrome exhaust tips complete the exhaust and provide a finished look. , , Quality Construction; This Injen Technology exhaust system is constructed from 3 mandrel-bent 304 stainless steel tubing for maximum flow and long service life. From there, every aspect of the system is hand TIG-welded by our experts in our Pomona, California headquarters.
