The Supersprint X-Pipe will delete the set of resonators ahead of the rear mufflers. By removing the resonators, you can get more volume and growl from your exhaust as well as decrease exhaust restriction for slightly better power and torque. Deleting resonators makes a small but noticeable increase in overall volume and also changes the sound with a little more rasp and rip. This x-pipe fits in section 2 of the exhaust - after the factory secondary cat section and before the rear mufflers. It is 65mm in diameter to fit the front and rear section stock piping. You will need to cut the original resonator section out of the exhaust, and the Supersprint is clamped into place.
