I have been told that going from my stock 6 cat. H-Pipe to an off-road H-pipe gives a gain of around 20 HP. Also, I have been told that with the off-road H-pipe and the flowmaster exhaust, a superchips stage 3 chip will add around 30 HP. These numbers (especially the chip's) seem a little fishy to me. Anyone have some accurate numbers?

Also, I am getting front and rear springs soon, and was wondering if the extra $100 for Steeda's competition springs instead of the sport springs is worth it for a daily driver.

Thanks a lot,
