AFE 49-04022 ATLAS 4" Aluminized Steel Race Pipe
2011-2016 GM 6.6L Duramax LML (ECLB, CCSB & CCLB Configurations Only - Does not fit ECSB)
The AFE 49-04022 ATLAS 4" Aluminized Steel Race Pipe for your 2011-2016 GM 6.6L Duramax is engineered to perform in the most extreme environments. This system is constructed from precision, mandrel bent 4" alumuinized steel tubing for maximum flow, increased horsepower, increased torque and lower EGT's. To provide a leak-free seal, OE style band clamps and flanges are used that offer a 360º sealing area vs. cheap U-bolt clamps used in other systems. ATLAS exhaust pipes are the perfect combination of performance, fit and value.
Installation is a Snap:
All systems use factory mounting locations providing stability and hassle-free installation.
High quality OE style band clamps and flanges are used for a complete 360º sealing surface. Standard U-bolt clamps used by other systems only seal at the bottom and top of the tube allowing leak paths.
Flow and Performance:
ATLAS exhaust pipes are constructed of precision, mandrel bent 4" aluminized steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT’s.
