Exhaust donuts?
Hey all I was going to put my EFI manifolds on my 78 and I went to buy donuts for them and they said that it doesnt use them?
I was really really confused. I have the Walker pipe, and it kinda looks like it would go around the manifolds, but just wanted to make sure. Also if this is the case do you have any suggestions as how best I can seal it, or does it just seal naturally(When I tighten it down)? Thanks

I *think* so, but be extra careful you don't over torque the fasteners. Those things are easily ruined. I do know that. I had a monte carlo V6 with no donuts, and it was over torqued by a guy at a muffler shop using a air ratchet after a exhaust overhaul. They always slightly leaked after that...Maybe someone else can give you a better answer...MK
