Stage 1 High Flow Bundle Kit for 2010-2012 6.7 Cummins improves airflow between the turbo and engine for improved efficiency, throttle response, and turbo spool up. Eliminates weak points in the factory design that can lead to boost leaks or complete failures in hard working and high performance applications. Replaces the poorly flowing, small diameter, crushed, factory pipes with our heavy duty, high flowing 3" Diameter Hot Side and 3.5" Diameter Cold Side Pipes. Kit includes upgraded high quality silicone boots that withstand higher pressure and temperatures than the factory boots to increase reliability and eliminate blown factory boots. Made in the USA from high strength, heavy duty 14 ga. aluminum tube with smooth, aerodynamic mandrel bends for increased durability and optimized flow. Full assembly finished in your choice of WCFab's signature custom powder coat colors for a look as unique as your truck. Installs with basic hand tools. Compatible with stock trucks, no tuning required. - - Not compatible with Banks Intercoolers
