I find it hard to believe different rings burning up, they go on the same engine and the temps coming out of it are all with in the same range and all made from same material, as far as using different rings tho you would get better fitment sizes. rings don't sound like the issue as much as why is the pipe moving so much to be breaking this tape seal. Iv heard so many issues with these pipes moving around so much and see so many cracked, welded, moved mounts on them. when a pipe is bolted up it should not move or wiggle at all, is this whats causing these issues for everyone? is it the exhaust wiggling? if that's the case than maybe adding an extra mounting tab somewhere, maybe 2 up front and 1 near back stinger. than with extra mounting now add a brand oring that fits and is temp rated, maybe add a second spring like some pipes use. Honestly Iv never messed with one so im just trying to blindly help, but theres always a reason for a problem and once the reason is found you can make a solution. other option is to get a turbo coupler at joint, hard to see how it would sit with all that stuff going on but maybe that's what ppl need? ill stay tuned, interested in how this turns out, as well as herps flange.
