Agreed, the wife noticed that little bit of noise...I told her I fixed the car so it can get better gas mileage. She doesn't know about all the other mods..."fixing oil leak, honey!"

I think one of the bigger factors when people install header is the removal of the cats, that alone more than likely makes at least 50% of the power. Since a large amount of restriction is removed, it would be interesting to see a dyno of just headers with cats installed to see what increase actually comes from just headers.

I ran catless for a few months, stunk up the neighborhood and didnt notice any power gains with my EC V7 tune. I'm running a kooks cat with MBH setup now.
