Alright, so I'm trying to figure which would be better to do; install a catback exhaust (kit) with a fart cannon on it or install a catback exhaust (straight pipe) with a fart cannon on it (if possible). I don't know much about exhaust topics so that is why i'm trying to figure this out. I have a 97 honda accord lx 2.2L.

 

Either one is going to be louder than hell. Get some ear plugs.

 

You're not really going to make any noticeable power with either. The only difference between a kit and a straight pipe/cannon muffler (yes its called a cannon, you sound like an idiot) is the kit will have a small muffler on the B-Pipe.

 

This is far too technical for my advice.
