aFe Twisted Steel 409 Stainless Street Series Steel Performance Package - aFe 48-42013-YC

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) 48-state legal 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 with an included extension pipe which allows this system to fit without modification. This system incorporates OE style hangers, flanges and includes O2 extensions for a hassle-free installation.
