Re: Headers to 2.5" Ramhorns
I have never mounted exhaust manifolds without gaskets nor have I seen it done. Why go through the work only to find out that there are leaks. Stock exhaust manifolds had gaskets. Why would aftermarket manifolds, most likely cast overseas, not need them? If it were me, I'd use gaskets.
