Exhaust work need some Assistance

I have a sohc neon and i just recently got a pacesetter header. I have a Dynomax muffler on it now. And i was wondering on what else do i need to get to have a pretty decent exhaust set up? I know im going to need piping but dont know what works the best? and what size should i get?... And then what kind of cat? or should i just get a resonator? and then would i need to buy a flex pipe? and then should i weld it all or just use clamps?? Also where should i buy it? modern performance, ebay, any other companies you can suggest will help.


Thanks all!!!

Get the 2.5" dynomax piping. Use your stock cat, flows well enough.

ok cool thanks bro for the help!
