I want my 02 maxima to sound like a 350z with a tomei exhaust. What piping do I need and what size does it have to be? 3inch is what I prefer, but I just want that deep and loud sound.

 

ok let me spoon feed you while your mouth is wide open, custom exhaust is your best bet for your 3"- 350Z sound , - custom modified altima headers or gut cats, warpspeed y-pipe, and carlton resonator, and 3" axle back . you are going to have to do alot of trial and error if you don't want to be raspy at 3" unless you do the carlton resonator.
