As im getting closer and closer to start doing some slight mods to my 2002 GTP i had a question as far as the order i do these upgrades go. I am looking into purchasing a performance chip soon and would also like to get the 3.5 or 3.4 pulley as well. Does it matter if i were to chip my car as well as put on a smaller pulley before installing new exhaust?? I wasnt sure if adding these mods will harm anything without having upgraded exhaust ? I plan to do headers and exhaust within the year just was not sure if these other mods will perform ok with the stock exhaust in the mean time. Thanks for your help guys!
