Exhaust

Cast-iron exhaust manifolds are mandatory and must be correct for the year, model, and horsepower claimed. Internal modifications to the exhaust manifolds are NOT allowed. Under no circumstances will headers be allowed, including those cars that came with headers delivered in the trunk. The exhaust system may be upgraded to a maximum of 2.5-inch head and tail pipes. Pipes must be routed as they were originally for the year, make, model, and engine combination. Mufflers must be stock looking in design, that is, oval in shape. No glasspacks or straight pipes allowed unless installed as original equipment. Maximum muffler inlet and outlet size is 2.5 inches. X & H pipes allowed.
