Try a custom exhaust shop that does a lot of street rods. Had a set done for my 1972 Norton Commando "S" by a custom exhaust guy and the results were beyond belief ($$$) . Stainless is the materiel of choice. :-DOn 2006-10-26 17:01, tcb wrote:
I'd be interested also, as I've cracked headers three different times right where the mounting flange is welded to the pipe. I purchased some sharks for racing clearance and noticed that they have a floating flange which lowers stress in this area and also allows for some flexibility in mounting.
