He probably had the DEF deleted and a straight pipe exhaust installed.

That will make it sound like that. I have a RAM 3500 feed truck on the farm I did that to. It sounds like a damn Mack Truck

I often see him in his truck in the end-of-day pickup line. It's a lifted, modified Ford 3/4-ton, probably an F-350.


Why is this dude even at the school picking up the kid?

Isn't that the kid's mother's job?

On my Cummins 1 Ton, there was a 'silencer ring' located in the inlet port of the turbo..



There is also a plastic insert in the tube from the air filter housing to the turbo the reduces turbo noise.

I'm just old, man. F-350 was definitely a 3/4 ton truck within my lifetime.

So, why did you put “So” at the beginning of this sentence?



I did that because the sentence you're referring to is explained by the one that precedes it. I'm not one of those weirdos who starts his whole post with "so" just because it sounds hipstery or whatever.

Which is wonderful to have. Turbocharger noise is obnoxious and potentially dangerous depending on the level.

You haven't known misery until you had to ride in a deleted straight pipe diesel dragging a cow trailer 4 hours through the hills.

People pay money to have to listen to that shite!

You should come ride in my Peterbilt- 13’ 7” stacks, no resonators. On a day cab.

You can only ride in it for about 45 minutes before it drives you nuts.

And the whole cab is layered in Dynamat.

ETA- but the kids think it’s cool- when the injector pump man asked “how you want it?” I replied “right before the connecting rods come out the block” “I got ya”

IDK about him, but I pick up the kid because I work from home and it's really easy for me to run by school and get her.

Seems wasteful, but I guess if you're towing something really heavy, you might want the turbo spooled up constantly so you get good throttle tip-in performance.


The energy the spins the turbine comes from energy that is otherwise wasted in the exhaust steam, so...it is not wasteful, whatever else it might be.

The thing about this truck that I find most noticeable is that it basically always seems to make a whistling turbo sound. I'm not sure it does it at idle, but if this guy gets on the throttle even a tiny bit, I hear what sounds like a turbo spooling up.


What your hearing is the wastegate dumping pressure from the turbo (the compressor side) into the exhaust.

I changed the Honeywell factory turbo to a ATS turbo. Better ball bearings better built turbo all around. Honeywell was prone to failure with shitty bearings.

Mine is a deleted 6.7 scorpion with a ats 67mm turbo. When I take off you’ll hear the wastegate dump the excess pressure off.

Its probably a f250, sounds like the truck has ben deleted. (all of the crappy pollution stuff) DEF is also deleted, Resonator deleted and then re-programmed. this adds about 150 to 200 extra horse power pending what program you get. Really lets the truck breath right.
