Do stock exhaust manifolds use gaskets??????
I'm almost 100% sure that GM did NOT use gaskets on the exhaust manifolds when they came off the assembly line. Nothing wrong with using them now though, they tend to help as the metal starts to get pitted.
Also the manifold face can start to warp. I use the gaskets they work good.
What gaskets do you use?
I used to have a pic of them at the link below,but deleted it the toher day...sorry. You can get the gaskets anywhere from the cheap ones (at local auto stores) to expensive copper ones at www.summitracing.com
Yes, they do. Try most any parts store. They are included in engine gasket kits.
yeh they do. i'd say if you plan on keeping the vehicle, go with the copper gaskets (so you don't have to do it again), as you can resuse them or retorque them!! i'v not used the aluminum one's but i'd assume they are about the same as the copper ones's??
Those are for headers. Manifold gaskets are really thin and shiny on one side and made out of what looks like cardboard.
