I'm extremely pleased with the gains from these additions.
1) Roto-Fab CAI
2) Kooks 6511-complete (1 7/8" LTH, catted x-pipe, mufflers)
3) Tune by R.P.M. Motorsports (Garner, NC)

My baseline dyno was done at ~1000 miles, the recent results ~2200 miles. The throttle response is tremendous, especially at low RPM. The sound is aural bliss! I was concerned it would be raspy, screaming, obnoxious but it's not. The best word to describe it is "aggressive". At idle and below 2000 RPM it's actually pretty quiet. When you hit it, it sounds just like a muscle car should

BIG thanks to Keith and Ryan at R.P.M. for their advice, great prices and quality work!

Here are the before and after clips for comparison. The first "rev" in each clip is to 3,000 RPM, the second rev is to 6,000.
