Restrictions in the exhaust system robs horsepower and torque especially on turbocharged cars. Thus, removing as much exhaust flow restrictions will increase horsepower and torque.  The factory secondary catalytic converter found in the factory midpipe is designed to muffle and quiet the exhaust flow however this causes a restriction to the exhaust flow.  Our Competition Series Mid Pipe deletes the factory secondary catalytic converters from the exhaust system to improve exhaust flow.  Coupled with mandrel bent tubing which also helps promote better flow, increase horsepower and torque can be had.  At the same time, a more aggressive exhaust sound is produced.

Our Competition Series Mid Pipes are constructed out of 100% 304 grade stainless steel and utilize mandrel bent piping. They are 100% TIG welded by our in house fabricators and built in the USA.  Our exhaust flanges are billet stainless steel that is computer CNC precision cut.  The factory bracket hanger is retained.  The bracket hanger is laser cut and TIG welded using stainless steel rods.  High quality  exhaust clamps are used to joint the mid pipes to the rear exhaust muffler section.

An added benefit to our Competition Series Mid Pipe is weight savings.  Our midpipes are a whooping 40% lighter than stock!  8 lbs (3.7 kg) vs 20 lbs (9.1 kg) for the factory mid pipes.

Our Competition Series Mid Pipes are designed to fit perfectly with either the factory exhaust system or your aftermarket exhaust system designed for compatibility to the factory mid pipes.
