: Broken exhaust bolt - replacement ideas?

Installed the Katech shifter and B&B today but after firing her up and finding a slight leak at the cat flange I broke a bolt by trying to snug it up too much. Surely I'm not the only one to have this happen. So before I head off in search of a replacement I was hoping that someone might point me in the right direction.

Thanks.

Shawn,

StealthV has a procedure for that on his website. You can also get a replacement threaded bolt from GM. When I installed my B&B I replaced all four bolts and the nuts. I see your located in Houston. I'm only a few miles away in Conroe. Maybe we can get together someday. I'd like to see your Katech shifter.

As Shane mentioned - When I twisted one of the studs, I used a 1/4" stainless bolt through the flange as a temporary fix while I waited for the GM replacement studs to come from the dealership. Your dealer may have them on hand depending on their parts inventory size.

Thanks fellas. I found some temporary replacements at Autozone as you suggested. The other three also broke as I tried to back them off. Luckily I had gotten enough extras. They ought to get me around for a few days.

Since the twisted day, I've had my exhaust on and off countless times - four times in the past two weeks. :cookoo:

What I've learned during that wrenching is spraying some penetrating oil on the threads or using anti-seize when putting them back together makes life much easier and the studs last longer.

Amen, StealthV - the penetrating oil is the key! I think I've had mine off well over 20 times now... :sneaky:

And thanks again for the replacement stud when I was in need.
