okay i'm still a noob here. so between the invidia N1, V2, and V3 which is the best invidia out there and what are the prices? will they all fit AP1? if so can someone show me a good site for it. thank you in advance.

 

A good site is the search tool.

 

I've got the N1 and its amazing, its loud as all hell but i havnt heard anything out there that i thought sounded better. i got mine from andysautosport.com for about $800 shipped. the fit was perfect, once i got the stupid stock exhaust off install was a snap. it comes in four main pieces. its simple. looks great too!
