I'm sure most of us here have heard a powerstroke that is strait piped. They tend to put out that awesome whistling/ jet sound via the exhaust. Even after the truck is turned off it expells that sound for a few seconds. I love that sound, I want it. Any ideas on how to get it, other than buying a ford ofcoarse.

 

my frind has a 6.0 powerstroke and it whitsles real loud, and he has a 4inchdp and 5inch ethe rest of the way. now straighted piped. look at summit he got it the summit brand.

 

You will never get the Cummins to sound like the 6.0. They are 2 totally different animals.

 

That makes perfect sence, so what would you recomend for more whistling other than a turbo?

 

Get a stage 2 cold air intake, remove silencer ring from your stock turbo or best is to get a turbo with a 71mm exhaust turbine wheel, 5" exhaust and no CAT. That will whistle enough to hear it in the cab and from a couple miles down the road. But, it's no cheesy whistle like a PS it actually sounds like a big truck.

 

 

Yep, that's exactly what mine sounds like.

 

but this one has a variable vane turbo, hes only adjusting the vaines on it, hes not even touching the throttle

 

That there sounds nice....

 

what the duece!! That's pretty cool, so can you adjust your boost on the fly, say pulling a hill just adjust the boost instead of the throttle?
