Center Pipe used for GT570/GT600 Racing Package. We have reduced the exhaust resistance by taking out the 2nd catalyzer and make the catalyzer straight for best result. There are 2 type, one with the silencer and one without the silencer. It's for racing only because there is no catalyzer. Part No. 33004-KN002
