I put them on this summer and after 3 defective sets gave up on getting a 4th. The only problem was the fit of the headers to the can. The can is supposed to overlap the headers but in all three cases they did not. I love the sound and the overall quality is good (except for the fit). The install can be difficult. Do a search for HK, I know there are others that have these pipes and have posted. You will also see my rants.
