I would like to stay under 4k at this time and really don't want to touch the engine.
So far after reading these responses I am leaning toward
Akrapovic exhaust
Stollen gen ii intake
Art resonanate test pipes
Anyone have any experience with nismo intake?
Also concept z performance has the akrapovic for 2195... Don't know of that's good.
