Exhaust System

LBZ & LLY Duramax Exhaust
Not sure if you see the exhaust you want with or without a muffler? Click on the kit you want, and you will be able to choose if the kit has a muffler or not from the products page!

Have a truck for work or towing? Check out the 4″ kits with a muffler, keep the truck quiet and improve fuel mileage, but these kits will defiantly let you know when you put your foot to the floor.

Truck mostly just for a little more fun? Check out a 5″ kit without a muffler, and get that deep grunty sound and hear that turbo.
