Well, not from me of course. The piping is made from the T-416? stainless steel (the borla stuff) so it is guaranteed from rust. The welds are very solid so I am assuming they are backed too. i would think the only thing that wouldn't be covered would be off-roading and scraping it on the ground. Right now it sits about as low as the stock exhaust and actually a little higher where the muffler is. I have to bring it back in either this week or next to adjust it because it think its hitting the differential or something. It was fine when I got it, but now it rattles a little under certain acceleration. The guys I'm working with are more than happy to check it out for me, and if there is enough interest I will approach them with the idea to mass produce.
