Muffler or Cat delete

[WV Diesel]

I have a 2007 6.0 and I don't have the money for big upgrades, but these new diesels are too quiet! I want to make her louder but I hate the turbine whistle. If I just cut the cat or just the muffler can I get the chatter w/o the whistle on a 6.0? Or do ya'll know of a after market muffler I can put into a stock exhaust to get it?
Any help greatly appreciated!
Thanks,

Get rid of them both. The truck will sound like a jet getting ready to take off when stopped, but it has a nice steady tone under power. I hardly hear any turbo whistle on mine.

What about back pressure? Will killing them both create problems with the EGR?

Nope. Backpressure on a diesel is not your friend.

If you take the cat or muffler out you will get even more whistle. It will have a little more rumble to it.

Any one have a good vid/sound clip of how this will sound? I was interested in doing it as well as a cheap work around to an aftermarket exhaust.

Also is it recommended performance wise, or if you can afford it should you just go with a cheap 4"?

LikeGoFastPadre said, no problems, all the backpressure your engine needs comes from the turbo. Opening the exhaust after the turbo helps it spool up quicker. The 6.0s have a lot of whistle and not a lot of the diesel chatter like, say, a 7.3, But an open exhaust whistles at idle and sounds awesome when you are on the throttle.


Oh, and What part of WV are you from??

The whistle on my 06 is barely noticeable at idle. I do hear just a tad as the turbo spools up but that is soon replaced by the sound my neighbors really hate LOL

Does anyone know where I can get a muffler delete pipe that will fit into the stock exhaust system. I want to be able to put it back to stock if necessary w/o cutting everything to pieces.

I bought my 3 1/2" downpipe and Muffler delete pipe from XDP. They are a site sponsor. You will have to cut the pipe before and after the muffler to put the delete pipe in. Mine is MBRP btw. Just punched out the cat and welded it back in so it looks stock
