I got a apexi N1 catback exhaust. The problem is the tip of it rusted off its pipe and is barly hanging on. The question is can i get a completely diffrent tip (brand) and bolt it on to the apexi catback or will it sound like shit.

 

Depends on what brand you buy and weather you have a cat and/or a resignator, all those along with the header is what makes up the sound that comes out of your exhaust. But the about any muffler will work with what you have, just have an exhaust shop do the welding.
