Lbz duramax or lmm!?!?

[martin53]

Looking to buy a new truck im looking to either et a lbz or a lmm. Plan on putting a 7 inch bds with 37s efi life & a nee fuel system , fass or air dog idk yet but cant decide if i want a lbz or a lmm please help!?

Depends do you want to spend extra to delete all the emissions crap or not. Personally I think the lbz looks better and I think the interior is better on the lbz, the lmm seems really cheap and is noisy.

As far as base mechanical goes they are pretty much the same

Basically the same thing once deleted. Choose the body style you like more. I like my lmm better based on the interior and exterior looks/comforts

I feel like straight pipe 5 inch ? Down pipe with efi would sound louder on the lbz. Is that true? What exactly is dpf and egr and how do you delete it

How do you figure you spend more deleting emissions? The same exhaust will fit both a LBZ and a LMM.

What do u mean cheap and noisey & i have a 04 1500. Same interir as a lbz

 

[martin53]

Yeah u can get a diamond eye 5 inch straight with egr and dpf

LMM, better resale value...

 

[martin53]

What do u guys think of efi live or whats best tune ? Anybody like ppe?

 

[martin53]

And fass or airdog fuel system

LMM inside is sweet (if its LTZ) and yes it will be easier to sell or will hold a better trade in value since it is the newer body style. I have had 2 and loved both of them:thumb::thumb::thumb:

I have had em all up to LMM. They all have pros and cons. I like the LMM better than the LBZ. Better looking once tricked out and better interior. LBZ interior outdated old school.

I still wish to this day that I would have bought a GMC LMM instead of Chevy. I think the GMC looks so much better in the front

Efi for tuning. Either pump is fine. I have mbrp dp and 5 in exhaust and it sounds nice and deep. You get rid of the dpf with turbo back exhaust. Block the egr.

 

[martin53]

Is a down pipe louder then turbo back

I like the looks of my SLT GMC better than my old truck, it does rattle more but I fixed mine very easily. And my LMM still books for 45k and my old truck did not.

With an exhaust only, it sounds like cats ****ing. With a full exhaust with the down pipe it is a lot deeper.

I have had a lb7, lly, Lbz, lmm. I love the interior (slt or ltz) on the lmm and General exterior looks of the lmm over the others. The only down side to the lmm is they are very fussy with tuning and love to go into "reduced engine power" mode a lot easier them others years but that can all be figured out with a good tuner :thumb:

 

[martin53]

May even consider an lml . Wanting 06-2012 maybe 2013

What do you mean. Here is what i want. Egr & dpf delete, so straight pipe 5 inch, to a 8 inch tip. I want loud & deep. Turbo back or a down pipe?
