i have my 04.5 cummins 2500 chipped with a 6 stage edge juice with attitude and six inch turbo back exhaust i really want to make my blow off valve louder what else do i need to do to my truck?

 

and where can i get a smoke switch?

 

there is no blow off valve, just a wastegate, there is really nothing that will make it louder, but you have the big exhaust already, but something like an AFE stg2 intake, will make the turbo alot louder, and the smoke switch is mostly a home made setup, just a toggle switch or button, hocked up to the map sensor wires

 

wow, just wow...

 

^lol....
