So I bought a grand prix gtp because I heard it is fairly easy to mod and get the engine to produce more power (why I didn't go with a gxp) but I wanted to know what are some of the cheaper easy ways to get more power I have been looking at zzp and was looking at a new pulley and saw they had a list of other mods I "need". I'm pretty much asking is it worth it to upgrade just to a 3.6 pulley I already have plans for a cat-back on the car aswell but havent found one that has really stood out any suggestions on what cat-back I should get (I like deep noise).
