Personally, I think the best power mods to date are exactly what I have. At least until somebody beats my 1/4 mile times. The mods I'm speaking of are:

* JoeZ intake pipe
* HKS drop-in filter
* HKS Hi-Power exhaust
* Removed secondary cats
* Lower profile rear tires (255/35-18)

Gernby, in regards to the additional power you are getting specifically from your exhaust mods, if you had to guess, what percentage would you attribute to each of the (2) mods? 75% HKS exhaust, 25% no 2ndary cats?

The only guess I could possibly make is to use the numbers that others have reported from similar mods (5 rwhp for intake and 10 rwhp for exhaust). I'm not one of the guys that trys to claim that they can actually feel such small increases in power.
