You may pick up some ET but the biggest thing you have to do is bolt on some extensions to prevent air going up the collectors and hitting the O2 sensors which would cause a pig rich condition which would slow you down

LAter:D

i dont think you would gain too much since you already have true duals but usually you will go alittle bit faster. also i think the noise is annowing

w/ a cutout on the stock exhaust I gained 2 tenths (0.200), and 2mph, and of corse all the other cars I run straight headers at the track, its worth a shot!

it may just pick up from the weight of the catback ur taking off, but watch the air/fuel change

Assasin, What kindah et's you runnin now? I see that you got your zo6 wheels on, what kindah offsets those wheels have?

Thanks for the replies guys.
