Features:
Construction: These unique up pipes are constructed of 2" mandrel-bent 304 stainless steel tubing with a .120" wall for strength and durability.
2" Inner Liner Flex Pipes: The down-pipes utilizes heavy duty 2" flex tubes with internal inner liner.
Leak-Free Seal: High quality 3/8" thick flanges are used for a complete 360 degree sealing surface.
Machined Ports: These manifolds have both the inlet and the outlet ports machined to match the factory gaskets. This allows for maximum flow, without compromising gasket performance.
Auxiliary Ports: An Exhaust Gas Temperature (EGT) probe port is incorporated into each manifold for easy installation of gauges or testing equipment. There are three additional cast in bosses provided to allow for alternate testing points.
Hassle-Free Installation: These manifolds are compatible with the stock up-pipes, which allows the manifolds to be installed without having to remove the turbocharger down-pipe or the up-pipes.

Y-Pipe Features:
Test Results:
Long Tube Headers:
Formed Collectors: 4-to-1 formed collectors decrease turbulence and increases exhaust velocity. The result is increased horsepower, torque and improved throttle response.
Optimized Tube Lengths: Tube lengths are optimized for true pulse control technology which improves flow and performance.
3/8" Laser-Cut Flanges: These headers come with 3/8" thick laser-cut head flanges and gaskets that are designed to match the head port for a leak-free seal.
Y-Pipe Dual High Flow Catalytic Converters: This system utilizes 400 CPSI (cell per square inch) catalytic converters are used for maximum flow.
Construction: Constructed of mandrel-bent dual 3" stainless steel piping which transitions into single 3-1/2" piping to reduce back pressure and improve flow
True Merge Collectors: Eliminates dead space that can cause turbulence and hinder flow.
Leak-Free Seal: High quality OE style flanges and band clamps are used for a complete 360 degree sealing surface.
Hassle-Free Installation: The performance header and y-pipe are designed to fit in the stock location incorporating the OE hangers, flanges and O2 sensor locations.

Tri-Y Design: Paired opposite firing cylinders with specifically tuned primary lengths maximizes scavenging and increases torque throughout the power band.
304 Stainless Steel Laser Cut Header Flanges: High quality laser cut 304 stainless steel header flanges provides superior sealing at the head surface.
O2 Sensors: Includes an additional bung for either a wide-band O2 gauge or auxiliary instrumentation.
304 Stainless Steel Tubing: High grade stainless tubing with a uniform brushed finish provides a beautiful look and high resistance to corrosion.
TIG-Welded: 100% TIG-Welded by certified craftsmen for race proven strength and durability. TIG-Welding provides the strongest welds reducing stress cracks.
V-Band Connection: Machined flanges and USA made stainless v-band clamps provide simple to install leak-free joints.
X-Pipe Balance Tube: The equalizer balance tube evenly distributes exhaust pulses traveling through the exhaust system. This creates a more efficient flow for better performance while minimizing exhaust drone.
Mandrel Bent Tubing: This system is constructed of mandrel bent, stainless steel brushed tubing for maximum performance, corrosion resistance and strength eliminating cracking.
