Yesterday at the track I noticed my bike was popping a lot on decel. Went back to the pits to find this. Any opinions if this can be fixed by a competent welder? Any ideas what would cause this. Other than a tip over in a corner it’s never been crashed. My guess is metal fatigue. Just haven’t seen this before and have owned many FMF pipes. It’s a TI header that’s about 2 years old.
