Thanks for those Garvino. That exit and mounting configuration is very similar to what I have in mind. Not much progress but I did manage to get the VBands welded onto my mufflers which was no small task. The mufflers are very light and have a spun end cap that is very thin (like .030"). The extensions are usually slotted and secured with an external clamp. I had to make a stainless spud that fit down in the muffler and into the VBand socket. Even so, it needed a close fitting aluminum plug made to sink the heat and keep the thin walled material from burning away. Turned out pretty good but took some doing. Will have to repeat this on tail pipe section.
Who are some good sources for the various styles of 3" entry stainless tail pipes?
