ZZ Diesel 3" Downpipe with 3 Bolt Flange

For 2015.5, 2016 GM 6.6L Duramax LML

Will work with a stock emissions compliant truck or upgraded. Constructed of stainless steel and heat wrapped to protect the firewall. Provides a smoother flow from the turbo by removing the restriction in the factory downpipe. This results in lower EGTs and increased performance.
