I hope for the best since I just went with ARH 1 7/8's from the hookers. No track or dyno #'s yet. Can't wait to see what your results are.

Car being the NON-dyno queen...it may see 8-10hp, but I bet you pick up a couple tenths and a MPH or 2. It's a definite upgrade, no downside at all - and that's no slight to the Hookers.

Stock heads will limit the possible gains seen. 10rwhp tops but now your are set for any future upgrades that these headers will be ready to support.
