Increase power and sound with a free-flowing x-pipe section that replaces the restrictive and redundant factory secondary catalytic converters for increased exhaust flow.                                       

This system was born through a customer's request for a more aggressive exhaust note out of his M-Performance rear muffler equipped M3, and when it comes to new development we are happy to oblige. We have developed a secondary cat bypass X-pipe to remove the restrictive factory catalytic converters and improve the sound. Up the tone without drone!
