Diamond Eye Manufacturing uses advanced CNC mandrel bending technology to create exhaust systems with smooth, consistent bends that eliminate restrictive crimps found in crush-bent systems. This DPF-back system connects behind the diesel particulate filter, allowing you to upgrade your exhaust while maintaining full emissions compliance. The 4-inch diameter tubing significantly reduces backpressure compared to the factory exhaust, resulting in improved throttle response, better fuel economy, and increased horsepower and torque. The dual outlet design provides a deep, aggressive diesel tone without excessive drone during highway cruising.
