I am looking around for a lower profile turbo intake elbow for my LMM, I see quite a few for the LYY that look like they would work (same size V band?)

I see them for the LLY but not the LMM on their site, (they do not list any intake elbows for GM above 2005) I see tons of them cheap for the LLY, not so for the LMM

OK, I see they use the same V band clamp or at least I see them listed for 04-1/2 to 10 LLY, LBZ and LMM so I am thinking they will work.
BTW there is no EGR on this engine

I would avoid using a factory lly horn at all costs. the s&b horn is pretty low-profile, and there are a few custom ones out there that are a bit thinner even. The factory LLY horn flows like complete garbage.

The LLY mouthpiece will attach to an LMM turbo, but as has already been mentioned, the factory LLY piece is garbage. If you're looking for one that is shorter in length where the intake hose attaches, the S&B is a very nice piece that will work well for you.

The LLY S&B elbow should work for you but I think the inlet diameter is 1/2” smaller where you clamp the intake piping too than the lmm intakes. I have one for sale if you are interested.

I have an S&B LLY coming, the smaller piping will not be a problem as it will all need to be fabricated anyway.
Thanks to all that responded!!!
