cold air intake,exhaust system,underdrive pulley kit,short trow shifter,computer chip so many options out there but i would do an exhaust system first..if money is tight...underdrive it

but the underdrive pulleys will void a warranty???

it all depends on your dealership. Best thing to do is contact the service manager and ask them how far you can go. Most will say that they will fix any problem on the car that doesnt directly link to the UD pullies. I have a full offroad exhaust and several upgrades and they have never once told me they couldnt fix a problem of mine. Like I said... it all depends on the dealer.

ya i dont know the guy was kinda a d*** i asked about getting exhaust and he was like it has a meter in the cats or something so i wouldnt do it blah blah and then he was like your car is fast enough you dont need to do anything to it......where do you live jdaniel, and what do underdrive pullies do for your car?

underdriven pulleys slows everything down,Its lenghtens the life of your accessories giving you a good 8-10 hp maybe more on some models

Im in Killeen Tx and thats what underdrive pullies do is slow the accessories down to allow the engine some free up room.
