I've got a 2.8 camaro, 85 with the stove pipe or whatever it's called on the right side exhaust manifold, does anyone know where to find one of these as they are disscontinued. I actually need the exhaust manifold, the bolts broke off in this one, at the pipe thing.

 

HI ! if the pipe or the heat riser is still good and all that is wrong is the bolt is broke off , have u tried to center punch it and drill it out with a left hand drill bit ? I usually go 2 or 3 times smaller than the bolt size just to give a little play, not to get in the threads . or if there is some of the bolt sticking out but isn't enough to where u can get a good grip on it to heat it and remove it, than i have used a tig welder to weld a **** or buttun on the end of the bolt to get a grip on it with a pair of viscripts ! I'm not sure on how much the exhaust manifold costs but would think that it would be cheeper to get the bolt out than replacing the exhaust manifold !!!!!!! If all fails, drill & re-tap. Just a suggestion :-)Good luck !!!!!!!!!!!

 

They are actually no longer available from dealer, I'm going to have to drill and retap, I guess.
