I want my truck louder then loud! if theres any way to make my turbo whistle louder please tell me! 02 7.3 4x4

 

straight pipe it, either 4" or 5", i have 4" on mine and its pretty loud, if you like the style (i don't) put it infront of the rear tire, you can hear a lot of turbo that way, but it'll also paint everything behind it black with suit

 

or just pipe it straight down to the ground i guess. or maybe hood stack depending on your state and if that's your thing

 

you'll have to weigh your options, cause if you put it anywhere but where it comes out stock, you're gonna get suit all over something ha so just all depends on what you want to clean more often

 

NONE

 

actually you could do a straight pipe to a turn down right behind the cab. you might get some soot on the axle but you really wont see it much

 

do a 4 inch down pipe to 5inch straight pipe out to stacks or tip.

 

Don't you want to be able to hear, siren, your radio, cell-phone, or your passenger

 

stacks

 

Big single stack should do ya.
