MagnaFlow Catback Exhaust 

This MagnaFlow (19281) 3" Stainless Steel Cat-Back Exhaust System with 4.5" Polished Tips comes with mandrel-bent 3" tubing in a straight-through flow design to get as much horsepower and torque as possible. The interior and exterior noise levels are engineered-balanced and tested against SAE J1169 standards, which means you'll love your Focus' new deep, smooth sound after you're done installing this new system! Proudly made in the USA out of 409 polished stainless steel, this system also comes with polished 4.5" dual exhaust tips and V-band clamps that'll make installation easier. Not only that, you'll also get a modified version of the factory valve found in your RS, but this new valve is meant to fit the 3" inlet piping. Plus, this new valve is integrated in the connection to your muffler, so you'll still get to enjoy the same features as your OE exhaust!
