I went through some fits as recently as last summer to get mufflers that had good chrome and no dents in them, so I think there are still some issues out there. However, so far, I am still really glad I got them. Like you, I love the way they look and ooooooooohh, that sound!!! Nothin' like it, IMHO!
I did not install them myself, so can't comment about that, but the finished fit looks absolutely perfect. The front heat shield is notched to clear our billet brake pedal, which I think some manufacturers are still not doing. With mine, they were still shipping the black powdercoated rear bracket that goes on the starter loose with some of the other hardware, so it had some slight scuffs which I poished up as good as I could and called it a day. Others have had to request replacements who's brackets arrived with more severe shipping damage. I think the jury is somewhat still out on whether or not the new bracketry has eliminated the earlier cracking problem since it took awhile for the stress cracks to start showing up in the first place. On the rattling, I think that was reported to be the baffles by one of the members here, but I have not heard a lot of complaints on that one.
Hope that helps. I would buy them again. I attribute the strong numbers I got from my Zipper's 575 cam swap (see sig.) to these pipes.
