I have an Apexi N1 Fart Can muffler.. I wanna make my exhaust quieter without draining hp. What do you think are the cheapest/best solutions?

 

best is obviously to ditch it and go out and buy an RS*R exmag...cheapest and still good option is to buy a 22" magnaflow resonator and get it welded into the piping.

 

Take a look at a P.I.T.exhaust, i just recently got one and i argue that its just as quiet as something such as the ExMag. I'm going to get some audio up soon...

 

whatever a P.I.T. exhaust is, it must be pretty local. seems like something you'd find at a local autozone/ other chain store... anyways, if you just have a n1 muffler on stock piping, you didn't really gain that much in the first place, so you could easily replace it with an OEM muffler without losing hp
