Twisted Steel Tri-Y Long Tube Header & Y-Pipe 304 Stainless Steel w/ Cat GM Trucks 2500/3500HD 20-21 V8-6.6L L8T

This system produced gains of up to +13 HP and +14 lbs. x Ft. TQ., as measured on our in-house dyno. This system is constructed of 1-5/8" - 3-1/2" mandrel-bent 304 stainless steel tubing for maximum strength and durability. Includes dual high flow catalytic converters which are less restrictive than the factory converters providing maximum flow. Factory style laser cut machined 304 stainless steel flanges are used used for a secure leak-free seal. Tube lengths are optimized for true pulse control technology which improves flow and performance. Formed collectors decrease turbulence and increases exhaust velocity. The result is increased horsepower, torque and improved throttle response. This system produces a powerful sound unleashing all available horsepower and torque. Utilizing a factory style flanges and hanger this system is a direct bolt-on system, which requires no cutting or modifications for a hassle-free installation. Utilizing state-of-the-art computer-aided design technology, this system is designed for custom, high tolerance factory fitment. 100% MIG-Welded for race-proven strength and durability.
