I just bought an '07 LTZ. I want to free up what ever HP I can and maybe some MPG's. I was thinkn ( as i have done on every car I've owned) CAI and exhaust. The forums members highly recommend the Magnaflow 12589. My next question was your thoughts on K&N filtercharger kit. Once those are installed, I was going for a BB Tune. Any input would be greatly appreciated.
