I'm lost and really don't wna round them sumbeeches off. Been soaking with blaster for 3 days now. Searched everything I can including part numbers.

Last time I messed with the exhaust I THOUGHT the bolt heads were 17mm. Maybe they’re rusted up and lost some of their size?

I wouldn't think to this degree but I suppose it's possible?

Mine were meant to be 17mm but had lost just enough size that they rounded off. I ended up having to cut it apart. Got a local exhaust shop to build me a new full system out of aluminized pipe for $300.
