Long tubes, Tuning, Bolt ons., Catback, short shifter. Its on the video also. Hopefully with the right tuning ill beat him without spray. He never pulled more than a car when i didn't miss. Everytime he pulls on me hard on the video i miss or i just let of. So hopefully i can take him all the way tru 4th with tuning. Then spray would be very unnecessary(for now). My goal was to beat a a stock 03-04 Cobra, and my friend beats a couple of them, so im happy
