Thread: Gibson Headers
12-11-2012, 10:20 AM #1
May seem like a stupid question....
Think I want to get a set of Gibson Stainless headers to pair up with my CAI and Gibson Dual Extreme Exhaust....
Went to the website to purchase and had two options...
With air injection
Without air injection
2011 5.3L Flexfuel......does it have air injection?
I don't think it does....???
