The first thing I installed was the Magnaflow cat-back and the mileage increase was quite impressive. Now I'm noticing that with the headers on my mileage has gone back down. Have any of you guys experienced a decrease in mileage after the headers were put on? Also, is anyone having a hard time keeping the bolts tight that holds the y-pipe to the header? I've had to tighten mine 3 times so far and they weren't just a little loose, they were a lot loose. My suggestion is, if you haven't checked them since the installation then do so soon. I'm either going to double nut the bolts or find some sort of locking nut because I'm sick of tightening them all of the time.
