Exhaust?

All 65's had the single pipe. Cosgigs relief is what it takes unless you want to go under it. IIRC the 5207 Hookers are built to already go under the crossmember. no clearance saved there. Buddy built (383, fenderwell headers) one that had the exhaust going out outboard of the crossmember, it was a hack job but so was the 383 fenderwells.
