3.5" Downpipe & Up-Pipe & 4" DPF Race Pipe & EGR Delete Kit For 2017-2023 Silverado/Sierra 2500HD/3500HD L5P Duramax 6.6L

This performance bundle combines a downpipe, uppipe, DPF, and EGR delete kit to comprehensively upgrade the exhaust system for compatible diesel models such as the 2017–2023 Chevy Duramax 6.6L and 2010–2014 Dodge Ram Cummins 6.7L. The downpipe and uppipe work together to optimize exhaust flow between the turbocharger and exhaust manifold, increasing horsepower and turbo efficiency. By removing the restrictive DPF and EGR systems, the kit reduces backpressure and improves fuel mileage, while the EGR delete enhances coolant recirculation for more reliable operation.
