EGR Delete Kit
Factory cooler setups recirculate soot and harmful gasses through your engine, causing build-up and clogs that lead to lost performance and proven mechanical issues. Cooler upgrade kits remove those concerns from the equation. Components install with an exact fit for a longer-lasting, better-running truck: less turbo lag for better throttle response, cooler engine temps, less weight, and a cleaner engine bay. Proudly made in Canada.

DPF/DEF Exhaust Systems
The exhaust is a DPF race pipe or a full 4- or 5-inch system (depending on what is selected). It replaces your old exhaust from the down pipe back, removing DPF emissions components, and is built to work in conjunction with the tuning.

Shipping: Free ground shipping on all U.S. orders. Kits are made to order. Check the product details for current lead times.

Returns: Reach out to our team to start a return or exchange.
