What is Header Coating?

 

We offer a number of coating options at a great price. Header coating makes your car run cooler and perform more consistently. It is not 100% necessary on a stainless header like this, but is great for someone who wants an extra edge at the track and lower cabin heat. Coating will add 2-4 weeks to normal order times. If this a concern, please contact us prior to ordering.

 

  • Constructed out of 16-gauge, 1-3/4" mandrel-bent stainless steel tubing for unrestricted flow
  • 4-to-1 formed merge collectors eliminates flow-block turbulence
  • Optimized tube lengths improve flow and performance
  • 100% hand MIG-welded construction ensures optimal strength and durability

Y-Pipe Features:

  • Constructed out of mandrel-bent stainless steel tubing
  • True 2-to-1 mitered merge collector eliminates dead zone for improved flow
  • Mandrel-bent 3" stainless steel tubing for better flow and added power

 

 

 

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.

 

Y-Pipe
Construction:

Constructed of mandrel-bent 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 that formed collectors are prone to produce.

 

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 hanger, flange and O2 sensor locations.

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 3" stainless steel piping which transitions into single 3-1/2" piping to reduce back pressure and improve flow.
