increased header noise ? For those of you with Kooks or QTP longtube stainless steel headers (and others as well) how much more engine noise have you experienced since installing the headers?
Not exhaust noise, but engine noise from the thinner-walled headers compared to the stock manifolds?

I was wondering the same thing. Just got my Kooks installed and at low RPMs as I accelerate I have a lot more noise coming from under the hood. the shop that installed them is very reputable so I don't think I have a leak, I'm guessing that's just the way it is. Is that the noise you have? By the way it goes away over 3000 RPMs and car sounds smooth and quiet up front, loud out the back...
