Construction & Design

The aFe Rebel Series exhaust system is crafted from premium stainless steel tubing, ensuring long-lasting corrosion resistance and durability under harsh driving conditions.

The system’s 3" inlet smoothly transitions into dual 2-1/2" outlets, optimizing exhaust scavenging and improving engine efficiency.

Each weld is precision MIG welded for strength and leak prevention, while the black stainless steel tips feature riveted aFe power plates that enhance both aesthetics and brand recognition. The wide center exit design is engineered to clear the factory tow hitch, allowing for a clean installation without the need for cutting or modifications.
