Hey all,
I'm the proud owner of a black diamond 2012 CTS-V Sedan, leased and then bought it out. So now comes the fun part. I have been stalking this site for a while and because of it I chose the Super Sports and Air Raid for my first upgrades.
I'm chasing HP and Torque without the hassles of a bad choice. Will I get this with a set of Kooks, stock mufflers and a tune. I don't want the usual header/custom exhaust maintenance issue that make me chase leaks.
I'm in Seattle and would appreciate any solid tips.

And why not an upper pulley and tune??? That's about the biggest bang for the buck than you can possibly hope for...and relatively bulletproof. Docile in town and a beast under boost.

Definitely agree with Trapspeed. Go with a 2.55" upper ( will need a different length serpentine belt ). Going this route will allow you to pick up anywhere from 50 -70 rwhp. Just make sure you get a reliable , experienced tuner who uses a dyno ( and not a canned tune such as Diablo) for the tune. IMO & FWIW, look for the AIR/FUEL ratio number to be right around 11.6/ 11.7, to be safe.
