BACK IN STOCK!!!
The LBZ mouthpiece is less restrictive than the LLY mouthpiece.
This product does not include billet plugs!

Made quite a difference in turbo spool up. Exhaust sound seemed to change for the better as well. Thanks Danville for fast shipping and having it in stock as it seems to be tough to get. Great upgrade for LLY's.

Definitely the #1 modification any LLY owner should do, the stock mouthpiece is way too restrictive and I've already noticed lower temps and quicker spool up. Also thanks Danville for great Customer Service!

Just installed and had a chance to run my 05 LLY truck unloaded. Boost transition is much smoother, and power is noticeably increased... No joke!!! EGT's are down about 100 degrees pulling up steeps grades. I did swap to a LBZ cold air intake, as the LLY intake does not fit LBZ mouth piece. A must do for anyone with an LLY!
