ESS Tuning - Stainless Steel X-Pipe - BMW E9X M3
Our E9x M3 X-pipe is a direct bolt on to the factory system. Our X-pipe design allows the M3 to gain power by removing the restrictive factory catalytic converters with either a high flow design or full catless design which utilizes a resonator in it's place. Performance gains are up to 15HP and 10 ft/lb TQ. Along with improved performance our X-pipe provides the M3 with a more agressive exhaust tone. The high flow cat version when matted with our specially designed ECU performance software will allow the car to be emissions compliant. The full catless option is not designed to be emissions complaint and is for off road use only.
