Just put on a set of the Mazzolini/ TTI Proparts 2 1/8 step headers, they are a pain and I don't have inner fenders.they touch the starter,oil pan,shock towers,transmission. They did however help my power. Mine is a low deck bb with Indy heads and Andy's plate. Only put them on to run last weekend, going to have some headers custom made, also gave me more tire clearance for 27" front.
