exhuast manifold studs???
i tried removing cat pipes to replace it with off road pipe and i am having trouble getting nuts off!!!!! i even tried heating up red and they are still very tight-------i broke one stud but i was lucky there was enough thread left to put a nut on. i stopped at this point------grrrrrrrrr-im peeeed off------------any thoughts, should i try heat then let em cool off??? or just go with it and replace any that break??? this car only has 1,500 hundred miles too.

i would love to take it somewhere like a shop---------but i am the shop, i own an auto repair shop and have done stuff like this since i am 15. these studs are tough to get apart. i ran into a similar problem with my buddys trans am, we ended with a project just to change front pipe.

We keep studs on hand. I've had to replace anywhere from one to all six whenever we remove the cat pipe. Also we double nut standsrd m10x1.5 nuts instead of the factory locknuts. Don't forget to use good antisieze on both ends of the studs. FWIW, I had to replace 3 studs on a 278 mile 04- and of course the 04 uses a different stud that nobody stocks yet!
