i have an 07 with a 5.9 what did they do to quiet them down so much i love a loud diesel what can i do to make it sound like an older diesel

 

Anew intake to the turbo, removal of the turbo silencer ring, new exhaust (or just no muffler and cat [obey all local laws, [sm=smiley2.gif]], most kits can replace both) and a new camshaft. I mention the last one because Diesel Power magazine mentioned one last year that added 10hp, 50ftlbtq, and 2-3mpg under all driving conditions. It also made the engine sound more like the old 12v. I'll go through my stowage bins tomorrow and try to find the article.
Now, since you said you have a 5.9 and not the new 6.7, you should be able to replace the intake and exhaust easily andremove the ring (free). The camshaft is more, but the est. cost should be covered in 30K miles.

Again, check with the pros here before going off my half-wit ideas, but they worked for me.

 

i already cut the muffler off i just have a turndown behind the cat but the older diesels just sound awesome i would love to get mine like that i want to pull the cat but i am worried about 2010 emissions

 

Well, mine was supposed to have a cat, but the dealer didn't know since it was a 04.5 engine. you could pull it and set it aside for 2010??

 

How does it sound with the turn down behind the cat?

 

If you are looking for that deep sound, get a Silverline exhaust. If you REALLY want your 3rd gen to sound like the older ones, get twin turbos.

 

it louder than a muffler delete it sounds good but i want to shake the ground like the older ones did will it get deeper if i add a programmer

 

On my 07 5.9 I put a mbrp cat delete pipe, bully dog cat back exhaust and a true flow xdi filter. It sounds awesome and alot of turbo whine. I saved the cat in case I need it in the future.

 

I have a friend who is a diesel mechanic that went to some cummings continuing education class. He said that the new engines are injecting a little bit of fuel on the entire compression stroke with a final burst near top dead center. Supposedly this is the main reason they have become so quiet.

so if i add a programmer that add more fuel do you think this would make it deeper
