I took the old headers to my local shop yesterday to remove the O2 sensors and they did it in 2 minutes, didn't charge me a thing
So I installed the AA headers last night. Why would anyone spend over a grand for exhaust cans that give +2HP when headers cost about the same and give 15-20HP and sound AMAZING! It sounds like I have a 6.2L V8 under the hood.
The sim is working perfect, no CEL at all. One problem though, since I installed the headers my windows are no longer one-touch going up. Could this be because of the sim or because my windows were down when I disconnected the battery? I don't really want to take a software problem to the dealer because they'll just void my warranty once they see the sim.
