Andrew, Ha... your a funny man.
I have made them modular. By that I mean that the collectors, sidepipes and cats/perf tube are three different pieces that bolt together. It's hard to explain (well it is for me), however I have turned up some reducers that also allow me to weld flange plates on the end of the cats that then bolt to the reducers internally and then just slide the outer pipe over the actuall working bits. (did I confuse anybody, cause I am now confused)
I have made TWO, but if you like I had a heap of fun making them and would be happy to do it again (if they work). I will bring them to the next "show and tell", and you guys can rip me to shreads over my welding.
