Armand; I have never seen a pair of street headers that are not flat on the bottom. Go to any swap meet and every one of them will be that way. A pair of short headers might be the way to go, where the collector is above the xmember. But you would be sacrificing clearence inside the bay. The only way would be to make a custom pair with specifically routed pipes of less than 3", or maybe fender well headrs and no inner fenders. But to just take a set of off the shelf headers, go down to Sams Muffler and have him bend up a pair of pipes, well your gonna scrape. I have seen pipes in street rods "flattened" to look like a fat ol pancake so as to clear the road. This is in really low cars and it looks like they are limited to weekend cruise-in queens only......Russ __________________________________ Do you Yahoo!? Yahoo! Mail - You care about security.
