What are the main differences in the 2 exhausts? I am selling one that I think is the hks that came off a wrecked car. It is not rusting, and has the burnt looking tips. Are there any other signs of a fake??
Thanks
Jim

yea around the upper canister in a circle patter are bumps, im not sure which one does though. Ill check tonight but im 99% sure that the hks doesnt have the bumps on the canister
