My current mods are 65mm tb, ported 2000 intake manifold, afx udp, flowmaster exhaust, prothane motor mounts, and bomz cold air intake. Would it be worth it to buy a fc offroad pipe, would i see noticable gains with this?
I'd say Yes, there'd be minimal gains, but not a big jump.
There's a Definite increase in Volume, and you Have to have an O2-Cheater to appreciate the gains.
It's your call as to whether or not it's worth it.
The FS Race-Header offers more gains for the buck.
