Well here, I have: WixAired CAI w/ 9" K&N cone, Autolite Platinum 104's plugs, 2.5" ZZP downpipe w/ Magnaflow HF cat, 180* tstat, and my brother owned a HP TUNER so he is going to tune my car for me a.s.a.p. I dont want to be like some of the NOOBS out there that basicly toss a 3.4" pully on a stock friggen engine and chip a piston. I might even go with a 3.5 if i can find one that not outa stock. What do you guys think? GO with 3.4" now or 3.5; or go with either with some more mods?
    You COULD always buy the MPS system...that way you can buy both the 3.5" AND 3.4" and swap them out vs. pressing on and off all the time

    Ive considered switching to magnaflow or borla, well pretty much any muffler thats not a chambered design. I'm still waiting for a used set to show up at my buddy's shop that we can try beforehand.
