Thanks stroker crazy.
I've been checking your Ace Resource daily. It's great to see everyones builds, ideas and comments!
Earlier in the piece i read about the exhaust guide you had used.

Especially the bit about the length required to make sure there is never zero "pulses" in the length of the pipe. Makes a lot of sense. Id suggest currently mine would barley have 1 pulse making it to the arse of the area of the Cat before fizzling out in the megaphone.
After taking the pipe off, it doesn't look like it would be too hard to have one fab'ed up. A bit longer, and maybe with some larger radii on the bends.
Being a draftsman and having a Dad who is wizard with all things stainless it shouldn't have taken so long.
If i get around to it ill up-load some specs so that others can get something similar fabricated locally.
