the RB exhaust is the quietest out there. if you want you can buy the 3" mp and 3" presilencer then have a shop redo the pipe from the presil to the catback. when you have the $$$ you can get the rest of the system



my TII is loud with the N1 !!! but i like it loud

 

i gutted my cats and still have the stock mufflers on it, its still really quiet, but it is a little louder, i just gotta fix those damn exhaust leaks!
