you running 2.5 dual exhaust? if you are i would stay with it, if not and youre 3" i would make a dyno with the cutout closed, reason i say this i lost with cutouts open on a 3" dual setup so i removed them.

you have any future plans to push the rwhp up? i bet you could reach closer to 500 pretty easy

i know what ya mean lol when on the dyno things tend to go blank
