CB-CAI Advice

[MinGry03]

I have two friends that both have 07 GT's. They are looking to upgrade some parts and I was wondering what CAI and CB/mufflers would be a great combo. Also, is a retune a must when you change to a CAI? Any help would be greatly appreciated.

A retune is a must. New "Oak" computer is quite sensitive. I bought Steeda's CAI from Brenspeed with their tune. I'm extremely happy with it. Also having a SCT Tuner with it, I can plug it in and change from reg/mid/prem gas. I also changed to Mac axle back exhaust. Nice low , throaty sound. Some say they "drone" but I have not noticed it. (I tried to make it drone, the only way was driving in 5th at 45mph)Everyone who has ridden in my car says it sounds perfect.I think its just right.
