what exactlly is a slip on exhaust pipe and why is it different than a normal exhaust pipe
not to sound dumb but i've been wondering

 

A slip on is just the muffler(the big bit that looks like an oversized can) at the end of the exhaust,and the header pipe is the long metal tube/tubes that conect the slip on to the engine.If you dont have internal mods youll be fine with just a slip on.

 

thx for the info
