I am going to be putting a turbo-back on my LMM. Is MBRP part #S6004409 all I need to get the job done? Does it come with the downpipe, or do I need part # GMS9421 as well?

Thanks in advance for the help!

yes sir, that's it

that other part # is just the front pipe.

let me know ;)

That is the correct application for the LMM, and includes everything you need. You do not need the GM part#.

Thank you both for the FAST replies! I also want to get Stainless band clamps instead of the standard U clamps. How many will I need?

Check out this picture from Tbyrnes "So you want to remove your DPF" post. I am counting 4. (This is for a crew cab.)

1lowdiesel - do you guys sell these band clamps?
