I have heard that replaceing the .84 turbine housing with the 1.15 turbine housing makes that noise cease. Charles, and others from the other site have said that before. And if you listen to any OBS truck (straight piped or not), they dont seem to have it, and they also have a 1.15 turbine housing.

 

The other thing to remember is that these are V8 turbodiesels. They will have a completly differant sound than a Cummins or even a V8 gas. I've noticed mine has a distinct lope to it.

 

take it off!!! I'll drive it past you, been wanting to drive a Tuned truck

 

I know mine is loud, may try that muffler!!

 

Ronnie your truck is not that loud. I have heard it, You should hear how loud mine is now. That's what the neighbos look like if i hop on it.

 

This is 4" straight piped Turbo back.

It's the diesel version of 2" straight pipes on a smallblock chevy sounds like an army of cubscouts at the 22 range.
Gotta have 13 liters or more through a pair of dual 5"ers straights with baffles...
No, really I havn't heard yours but Iv'e heard alot of them in my opinion it doesn't sound like power, just tuner noise like a fartcan on a honda.
Bet it would sweeten up with a spiral baffle to knock down the "PAP" and give it some rumble. something about diesels I read... turbo mufflers make them rumble and round mufflers or glasspacks quiet them down. supposed to be opposite of gas burners, why i don't know but found it to be true on non turbo diesels.
black smoke is often wasted fuel, high volume but low injector pressure, high exhaust temps, not enough turbo or head flow. maybe timing too if everything's set up right there's a small puff till the turbo lag catches the fuel curve.
The factory pump is pretty much tuned to the fuel usage. Software tuners move fuel pressure from the upper curve to the lower for more botom end power but the pump can't can't keep up when the rpm's come up and the power drops off... adding pump capacity keeps the line pressure up.

 

Like Jeremy said but at our next GTG, let Jeremy take it for a spin, he'll love it, then he'll want a DP, lol.

Before my MBRP duals I replaced my stock muffler and got a glasspack, sound was nice and mellow and was not that much louder than the stocker, just sounded better. On the discusion on your miss Caleb, keep an ear to it, if its truely a miss, you'll know it. I never had anybody ask about a miss in mine, i,m sick of hearing "You must not get good gas mileage with that", car driven mileage worring turds, I tell them I get an average16-18 miles to the gallon and I get this look. What were we talking about, lol...

 

So what's the difference if you spend $5- $10 a day at 12 mpg doing business or spend the same $$$ buzzing all over town in a golf cart???
I've got a 460 hasn't used more than $100 of gas in a couple years

 

some of my co-workers say the same thing that my engine is missing but they dont know nothing.Does it sound like this.......
