Hello Guys. I'm back with some more questions about my GS. So I currently want to make a custom exhaust from stainless steel myself.. obviously a pipe that's already ready to be cut sort of thing. Yes, I understand that basically straight piping the bike is bad and will create a vaccum to suck cold air in, yes I know. I understand all of the risks. What I do not understand is what to use and where to even start? It's a 1990 GS500E. I want to cut down past the can about maybe 6-8 inches and create an outer facing hole so instead of the exhaust end-hole facing behind me, it faces directly to my left or at an angle towards the back. Someone please fill me in on how and what I can do to get this started.
