Hi

I'm interested in a 2.75pulley,100mm upper idler and predator

does Amazon Racing have these products?

I have an offroad xpipe and cold air intake

will the car run stronger?

apreciate your responses

I'd get a cat back if I were you but I dont think it is necessary. Your car will be a whole different car after the 2.75. It will be a beast!

Let us know I have yet to do the pulley. I have ridden in a buddies pullied 03 Cobra and it made my car feel like a soap box derby.

You're also gonna need plugs. I would get cats on that mid pipe cuz your loosing boost without them, and think about a cat back too.

You can see my sig, and Rick at Amazon did great work.. Going back tomorrow to get an exhaust leak fixed on the headers, then gonna take it to the track with new tires hopefully on the 17th. Should be good for 11.80s..

Amamzon will have anything you need..

yup, go with the pulley, idler and predator.. it has made my car that much more fun to drive. I did intake and exhaust first, but I regret not doing the pulley sooner.. You will love it. Pretty sure Amazon racing carrys those products, best of luck!
