So I have had my shockwave for about 2 months and I have the itch to put some new exhaust on. Looking for something thats gonna sound great and add some power on the stock 1998 454mag. I have been eye balling the EMI Thunder exhaust or the Dana Torque Flow for a bit but does anyone have any other suggestions that won't make my wallet puke?:skull Also has anyone ever put this tuning kit on their 454 mag yet? http://www.cpperformance.com/p-13681-ss-sport-series-tuning-kit-for-mercruiser-454-502-magnum-mpi-engines.aspx Or would I be better off sending the ecu to arizona speed and marine to have the ecu reflashed?
