    bought for 2014 gt500

    Sounds excellent and performance gain is very noticeable. Did this upgrade with the Kooks long tube 1-7/8 header upgrade to delete all 4 cats on the car. X-pipe install takes about 20mins once the car is lifted up. Please note, the car's stock exhaust manifold comes with SHORTY "headers", i upgraded to kooks long tube headers and this shorty x pipe. So the x pipe could not be installed without doing the headers first. Totally worth it. Dont even bother looking at other products, buy this one w/ the headers :D Did not throw a CEL.
