Just added Jet hot header and off road Y & dropped 2mph My best on street tires was 13.0 at 111 granted it was a cool night with a little tail wind. I installed my header and I ran a best of 13.1 at 109. It was a warmer night but I thought for sure I would pull a 12.8. It seems to pull harder but it could be all the nnoise coming out the rear psycing out. The only other factor are I ran 10-30 synthetic instead of 5-30 and I removed the Fast Joy Ram Air because I didn't have the air box sealed properly and I figure the ram air free mod allowed mor air to get in because it has a larger inlet area. I don't know what do you think. It was 10 or so degree hotter and slightly humid compare to last week when I ran my best. 
Also, how do I get rid of that nasty rasp. It made my MAgna Flow catback sound crappy.
Thanks

Re: Just added Jet hot header and off road Y & dropped 2mph Its hard to say why you ran slower since you changed some things up between running like the air box.
