I have had the headers a few weeks now. They rule. The only thing which I notice is that there seems to be a new sound when I am hard the gas and then shift gears. I am not sure if this is from the CAI or the headers or simply a result of improved intake/exhaust. Is this normal. Kind of a whooshing sound (yeah I know - very technical). Only seems to happen in 1-2, 2-3.

CAI depressurization...normal

 

Get rid of the AEM, go with the Icebox and the car will sound normal and perfrom better.
