Construction & Design

The SES5006AB exhaust system is constructed from premium 304 stainless steel, offering superior corrosion resistance and durability compared to standard 409 stainless steel commonly used by competitors.

The low-profile oval muffler is designed to fit neatly within the vehicle’s chassis, protecting the system from damage during off-road excursions.

Every weld is meticulously TIG welded by hand, ensuring exceptional build quality and longevity. The high tuck design positions the exhaust higher and closer to the frame, reducing the risk of impact from rocks, debris, or rough terrain. This thoughtful engineering makes the Injen High Tuck Axle Back Exhaust a reliable and rugged choice for serious off-road enthusiasts.

Compatible with both the 3.6L V6 and 2.0L Turbo engines, the system produces a deep, throaty tone that is unmistakably Injen.
