Hey guys,

Im really new to exhaust systems coming over from a r50. Basically my friend owns a shop and has agreed to help me weld together a cat back system.
I want to get some info from what you guys have in order to figure out that best way to route the exhaust. I plan on just cutting off the stock pipe and welding the same diameter re routed.
I want to know.
1. What type of system do you have?
2. What diameter piping

 

I had an R50 with a Borla system. I would have never payed what the previous owner paid for it, but man it sure sounded nice for a NA 1.6l.
