I have that kit on my LMM. It looks great. I like Nathan's relocate of the fuel filter. It makes for easy changes!

Hows it run? :D and with the filter relocation will i still be able to run my nicktane adapter and cat filter or will i have to go back to stock Nathan was not sure he said it would be close

It runs great! Spool up is a little slower than my LLY with MPI twins. I'd think the nicktane adapter would fit. Or if it don't, it should be easy to space out so it does while the install is getting done. The sound of these twins is much quieter than the LLY, but the LMM still sounds great. Do yourself a favor and get an exhaust that fits the LMM Trans mount bracket on the front pipe. The only one I know of is FloPro, but there may be others. The turbo resonates at idle without it. I changed my idle rpm to make it better, but its something better fixed by mounting the front exhaust pipe on the factory Trans mount. What color coating did you choose?

I might feel bad for you if I hadn't already removed my perfectly fine 4" system to install a 5" MBRP 409 system because it looks better.....then install a 5" 409 flo pro on another truck to realize the rear tailpipe on the flo pro looks way nicer and the flo pro has the LMM Trans mount to fix the vibration issue at idle. So guess what I'm changing again? I also got some MA motor mounts to install. That should cure the vibration once and for all!

X2 on vibrations. Mines not an lmm but i have 5in and the dam thing rattles when u shut it off. The 5in is just so dam tight. Sucks. I also have merchant mounts that i need to get. I believe it will help. Other then shut off mine makes no noise tho.

Your exhaust should line up with the Trans mount since you have a LBZ. I've got a way to fix that shut off vibration. Real easy fix!

That would be sweet. Cause ive played with alignment on it so many times. Ive got pretty good now but I think the motor mounts would do the trick on what very little rattle is left. But im open to hear your options.
