I know about the clicking noise that come from our engine but that is completely normal. This header noise is weird tho. I don't think is nothing major since I don't feel any loss in power or anything different. Plus this noise been there since the first day I installed the headers. The noise get more noticeable the colder the weather get and is only audible with the windows up and almost wot.
I also been thinking, maybe I am defining the sound wrong. I think the term flapping or tapping is more accurate?
lol I don't know. I am very anal when it come to my car and things that I think that are abnormal. Maybe all this is just nothing and completely normal for long tube headers. Only experience I ever had similar with my own car was when I had the HKS bellmouth downpipe installed and that made tons of wooshing and different noises, but that was also on a turbo. I get something similar what sound like turbo spooling with these headers on my camaro too.
Thanks guys.
