Performance - What to do?

I have a CAI with Brent's tunes. What is the most beneficial mod in terms of performance next to this (other than SC/Turbo/Nitrous)? Where do I go from here?

I would like to hearpeolpe have to say, I've been thinking the same thing. I bet most are going to say gears.

Gears arent an option for me since its my DD and its nearly all highway miles. Gas mileage is important to me. How much HP do H-pipes with high flow cats put out?

H or X pipe, with or without cats
Long tube headers (don't bother with shorties)
1 piece driveshaft
Underdrive pulley
Electric water pump
CMCV delete plates
Torque converter (if your and auto)
Gears

not much hp at all.....even considering your highway miles, i'd still say put in gears, if 4.10s are too steep, go with 3.73s.....they'd be a good jump from your 3.55s and the negligible rpm increase wouldn't put a dent in your pocketbook.

There are also 3.90s that are a good middle ground if you don't want 3.73s or 4.10s.

IMO CAI, Tune and gears are the big three for a N/A car. After that it's all incremental. go with the Gears.

Just so you know, if you get a midpipe with either high-flow cars or no cats at all, your exhaust is going to be crazy loud because you have Loudmouths.
