LBZ: LML Manifolds and Up-pipes

[LBZ]

I've heard the LML manifolds are bigger and am thinking about using them instead of just a BD on my driverside. Is this true?
Will they bolt right up without having to mess around?
What about the egr part of the P/S up-pipe? Can a guy just cut that off and weld them up?

I don't think the up pipes will work or if they do its not worth the time or hassle to put them on. But yes the driver side lml manifold will bolt right up and it is not necked down like the original manifold is. $100 at the dealer. I put one on my truck and haven't noticed a single difference.

 

[LBZ]

Hmmnn. So the LML manifold will bolt right up to the LBZ up pipe then your saying. Good to know. And ya for $100, way better option.

 

[mike diesel]

Yep, it bolts right up to lb7-lmm up pipes.

I'm fairly certain when I looked up that manifold in Red Deer, it was over $200.

Danville sells them too and they are less than 100

Just run with a LML manifold on your driver side and a LB7 uppipe on your pass side! Everything is bolt right up! You can get the manifold off gmpartsdirect.com for less then $100 shipped!

the only thing i had to do was tweak the heat shield a little to get it to fit back on the LML manifold but other then that it was super easy, hit all the bolts with PBblaster before you go out to actually do the job it really helps.

I paid $67 but i get everything at cost. Merchant Auto has then for right under 100 as well.

 

[LBZ]

Cool.
I already have a fed up pipe on the P/S.
manifolds are all coming off anyways as the heads are going in to get resealed and checked out so manifolds will be off anyhow.
I'll get my GM tech buddy to check out his price and see what he can get them for.

Allseasondiesel has them with a new heat shield for a 100.

 

[hondarider552]

Ain't nobody got time for heat shields.

 

[OregonDMAX]

the driver side manifold is redic close to the IC boot on the LB7...is the heat shield making a difference at all or no?

 

[c20elephant]

Plastic fender liners come to mind, on a long drive with glowing manifolds with outside temperature's at about 90+ and no heat shields could potentially melt the liners.............I prefer not to chance it.

If that were the case, then every one of us with aftermarket manifolds would be having big problems. You'd also have heard of issues with BD manifolds b/c the heat shields didnt fit well over them.

 

[LBZ]

I'd be more worried about glow plug wires.
I'll make it work!

You probably will not have any problems as you live in Michigan, please read the last words in my post............."I prefer not to chance it" I live in Phoenix Az. average summertime temperature is 100.

 

[OregonDMAX]

same here, although not phoenix temp i still saw a month of 100* straight, id rather not chance it since the heat shield took literally 30 seconds to modify...

Lol it doesn't make any difference C20. I would have a melted fender liner or hurt my intercooler tube by now.

Your under hood temps and egt's might be different from an 02 to my 06 with a cat-con and stock exhaust. Lots of differences to contend with to make a comparisons from my truck to yours........:thumb:

It doesnt matter, they both at just as close to the fender liner and hot intercooler pipe as the older years and run egts waaaaay cooler in stock from than i do any day regardless of what emissions equipemnt is on it. I can prove that it has no affect where heat, pressure, temps are way above stock. It's easily seen by the fact nothing has changed either of the parts in question.

Yours being stock would only better the chances of "said issues" not happening
