I just installed my kinetix race pipes and plenum and the car definately feels different but im not sure if its in a good way. It seems to me like the RPMs may be going up slower then before and the car definately doesn't have as much response when you first give it gas. So I guess it seems like I lost some in the low end which I dont care as long as it makes it up at higher RPMs. I just wanted to know if others who have done this have felt the same thing. I definatley think it has to do with the race pipes and not the plenum but I could be wrong. Any imput would be appreciated. Thanks.
