Hey guys, got a quick question for you. I have the usual 03 mods ( lightning pulley, Accufab throttle body, 9" filter and shield, Metco idler and Amazon Diablo chip) but still running the stock exhaust. My question is related to my trap speed in the quarter. The very best to date is 116mph (usually in the high 114mph to mid 115mph range) would a better exhaust help me to reach 120mph? The reason I ask is most of the other 03's here seem to be trapping 120mph plus with more or less the same mods, but with an aftermarket exhaust. I know I should change exhaust I just can't make up my mind what to get. Thanks in advance for any replies or suggestions, snakecharmr99.
