Re: surface rust on hotdog muffler, still ok??
Basically, as long as when you put your hand over the end of the muffler it holds pressure, does not leak, and has no exhaust bandages on it, they should pass it.
Alot of exhaust places have good stuff in the throw out bins, if you ask nice they let you have it.
I did put something here, but it vanshied, I think
"So long and thanks for all the fish!"
