I am thinking of upgrading the exhaust. Just wondering if it will be worth while? I treid a superchips flashpaq and did not see any great improvements. Looking for help with best possible options.
I would always say yes to an upgrade on exhaust.But even more so on the 5.9 it helps engine "breath" better and depending on exhaust system u put in u will increase hp slightly.plus it make the "rumble" sound even better:D
full exhaust, CAI, chip, and thermostat all combined properly will give pretty good gains.
