[Beyond]

Tried fixing an exhaust leak on the Dually. At first I thought it was just a donut leaking, so started out replacing that. Broke a stud off on the exhaust manifold trying to get the tail pipe off. So I figured I'd take the manifold off to drill the stud out and replace. That's when I noticed about a 4" long crack down the side of the manifold. Pulled it off, back side was cracked too. Took it over to my father in law's and he welded it up for me - not sure if it will hold or not but going to give it a shot. Should know this evening try putting it back together. If it doesn't hold I'll put a set of headers on it.

I've had several people tell me their 454's got worse gas mileage with headers? Anyone have a simlar problem? Was thinking about getting some of those Summit headers for $79.95
