Header Features
High Flow Catalytic Converters:
Each header comes with 200 CPSI (cell per square inch) metallic high-flow catalytic converters for maximum flow.
Mitered Merge:
A 3-to-1 mitered merge collector decreases 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.
CNC Laser Cut Flanges:
Flanges are CNC laser cut not only to be visually appealing but for a durable, precise fit and leak-free seal.
Y-Pipe Features
Massive Y-Pipe:
The massive y-pipe is designed using a mitered merge that utilizes a 2-1/2 IN to 3 IN transition for optimum flow while removing turbulences.
True Mitered Merge:
This system utilizes a 2-to-1 mitered merge collector to eliminate dead space that can cause turbulence and hinder flow.
Retain Factory Sensor Mounting Locations:
Retains factory sensor locations for a hassle free installation. These headers also include 400 CPSI catalytic converters that are a direct bolt-on installation which requires no cutting or drilling
