I have an 05 grand prix gtp. last summer i ran a 14.83 @ 94mph. all i had done to it was an auto zone spectre intake. im going to be getting a 3" downpipe with highflow cat, a wizaired intake, power log, and a tuned pcm. i also just got some motegi rims that are lighter than my stock ones and i just got some way better tires. what do you think i will run in the 1/4????
