My project involves fitting an Ariel Arrow engine into Royal Enfield Bullet rolling chassis. My Mig set has been fine for the frame mods, new downtube etc, but the exhausts have been a major challenge. I am using TDR exhausts which match the dimensional requirements of the expansion chambers, but have a cross over feature to achieve the correct tuned length. The material is 1mm thick, borderline for my mig. Picked up some Honda NSR250 mufflers, but now require a connection pipe with a few bends. I'm looking at R tech PDC 160.as an entry level tig set.
