CNS Racing BMW E39 M5 - CAT-Back Power Exhaust System 1999-2003

***This is the special CAT-Back version of the CNS Racing Power Exhaust System. This includes complete plug and play mandrel bent stainless steel piping and a handcrafted X-pipe.

A vehicle's exhaust system is one of the most important factors in engine performance. The pipe size and flow rate have a direct effect on horsepower potential. With a non-sufficient exhaust flow, your engine's full potential will not be realized.

The exhaust system finalizes and determines the full potential of a modified engine. A high-performance exhaust system will allow additional engine modifications to come alive.
