My 2007 Grand Prix GXP, with K&N CAI, custom hood, magnaflow exhaust... :(. I've missed it... that LS4 has some pep. Though, I saw the greater good and sold it as soon as I realized I'd be buying my Camaro... this was over a year ago btw and I'll be taking delivery of my 2011 2SS/RS in two short weeks.
