the only current modification is exhaust. I have a 20 inch glasspack behind the stock cat with stock diameter tubing. it exits in front of the rear passenger side wheel. mandrel bent (no kinks). my wife had it done for our first aniversary as a present. anyway, I'll have to change the aircleaner any way you look at it because the flange on the 1 barrel is 2 5/16" as oppose to the 2 barrel which is whatever a standard 4 barrel is. should my exhaust and a 14 x 2 inch open element filter be enough to notice a difference?
