Trying to mod some Triumph mufflers to fit on the XS with stock headers, and I need to do a slight adjustment to the header discharge angle just aft of the frame mount because the muffler hits the shock bolt....
Basically, I'm going to cut the '77 header backside, just aft of the frame mount, clear through for about 1/2 the pipe width, tweak the remaining about 4" of pipe out until I have about a 1/8" void, then... carefully... weld the double wall void I created.
Should work, but I'm not sure of the double wall issue. The inner pipe is thicker than the outer, so they my expand at a different rate when hit with a MIG/TIG? The ebay set of headers I'm using are also pretty rusty inside for the area I'm working in.
I'm more of a tacker than a welder (in that my welding skills have greatly increased my grinding skills...), so my modus operandi is to fab the work, tack in place, then take to a really good welder for completion.
With all the different threads on here about exhaust, could not find one on bending the stock headers. Don't see a reason for this not to work?
TIA
