First off, HAN was down for so long, that I got really bored. Anyway, my question. I found this idea on another Forum. On my 96 Ex Civic, can I put on an 00 or 03 Si muffler on it instead of aftermarket? Would I see better performance?

If so, anyone know where I could get one?

 

probably not even noticable, and why not just spend the money to get an aftermarket one.
