Nearly brand new FMF 4.1 stainless pipe I bought for my 2006 WR450. I used it for <5 hours and it still looks like it just came out of the box. There's not even any black exhaust residue on the inside. The box it comes in says Titanium full kit but it's not, it's only the pipe (and mid-pipe) and it's stainless steel. Screw and spacer come with it.
