Stock mid-pipe to muffler bolts
 

I was helping a buddy install some test pipes yesterday and we couldn’t get the nuts loose off the mid-pipe to stock muffler. So we cut them. Little
Did I know that those bolts don’t come out. So unless we drill them out somehow, is a new mid-pipe our other option? Thanks guys

Those studs should come out. use a hammer and chisel and some PB blaster. Or a drill.

Man, I put pb blaster on them and let them sit for about 8 hours and hammered on them non stop and still got nothing. I’m not sure if they’re just really rusted in or what...

Air Hammer?
And you're hitting the threaded part towards the flange right?
I know that sounds self explanatory but you wouldn't believe the **** I have seen over the years.

Yeah, you messed up. Those studs are welded in. You will need a torch to cut the welds or get a used midpipe.

^^^ That. A little heat from a torch may also help.

Wrong section too. Next time, post in the Intake/Exhaust section.

My bad.
