My headers are starting to look pretty shocking now with one now coming away from the engine but is still sealed, so it's currently got me going through my exhaust options.

anyway looking at the bolts that go over the studds from the engine, they look like they will be putting up one hell of a fight which will be ending most likey in their destruction. Is there a better alternative to using the yamaha bolts? i can see the advantages of keeping the studd and nut arrangement, but they could also just be swapped for stainless bolts.

Which ones have proved most reliable?
