Thats right pass side same thing now can't trust either of them! Not happy and don't wanna spot weld the nice stainless just to trust it! Going to try normal muffler clamps first!!! The ones they supply are to wide and didn't force the strong stainless muffler to pinch the tailpipe maybe they pinch there weaker non-stainless systems fine??? "If that tail pipe lays over it's pretty perfectly lined up to scrub through brake line and not a happy place to fix spot. Put car away for now but will comment if normal muffler clamps work.

Sounds awesome! Stainless won't rust. Would have been 5 stars if the clamps would hold and the passenger side wouldn't have needed modified to fit. Did I mention that it sounds awesome!!!
