I have been doing a fair amount of exhaust work lately so I went out and bought a welder, cut off saw, big air compressor and all the other goodies I need to do it all at my house.
I like to do mostly stainless steel work, but I can also do mild steel if you are on a budget.
I have made a few systems unlike any other on the market. It is mandrel bent 3" stainless steel O2 housing. It is extra long so it can be run alone at the track. I connect that with a stainless steel V-band clamp to the down pipe. This makes it so that you can drop the exhaust with one bolt! I will have my system done shortly and I also did one like this for Brian Barton. Here is a pic of his:
More close-up pic's coming soon!
