#1963, "RE: Addition of Greddy header" In response to In response to 4
O.k. I have the greddy header and it's great when the rpm's are up. Until then the engine feels the same. As for churping the tires well I can get the O.Z. wheels to do it but the 18's on there are a little tuff. As for you 1/4 mile time If you running 18.5's now expect another 10th to come off. My car was running 18.53s until I dropped some weight got a 17.91 last week.
