by AFE

Product #: 48-42013-YN

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.

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.

Connection Pipes (Race):
Performance and Sound: This system was designed as a "Race Only" version for added performance and a more aggressive sound.

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

Factory Mounting Locations:
3" diameter connection pipes mount directly to OE mounting locations.

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.
