6.0 gas performance mods

Copious you guys point me in the right direction as fast as how to add power gradually. I.e. what order would you modify which parts? Thinking exhaust first only because i want more aggressive tone. Not super Loud though. Suggestions for Suggestions systems are appreciated as well

Exhaust is going to do just that, add sound. No power gains, and if they do, its like 5hp at 5500rpm. Never noticed. That said, Corsa, MBRP and Magnaflow make them for the HD trucks. If you want power, you've got to go custom tune for 91 or say even E85, or add some forced induction.

I like forced induction. Quite a bit of coin, though. Supercharger and exhaust, should be good with the tune provided by the vendor. 6 grand right there.
