Post by neoncrazy101 » Tue Feb 20, 2007 7:27 pm

well i wasn't sure on where to ask this so yea lol...but how hot would you say the exhaust piping gets? cause i'm going to be putting JB-weld over some joints in my straight pipe to make sure theres no leaks and make sure they stay together but i read that JB only works up to 600F. so how hot would you say the exhaust gets?

I found personally that j-b weld is crap on anything that gets hot or cycles from cold to hot then cold again..... just weld the sumbitch... :D

I have a pyrometer on my R/T before the cat and at WOT runs, I've seen it get as hot as 1200* F

Best bet would be to weld it. But if you don't have access to one, permatex has a product specifically made for exhaust patches. Working temperature up to 2000* F. I've used it before and works. But ideally it would be better to use a welder.
