Installation and Tuning Tips:

1. Do Not Uninstall Parts Before Receiving All Components: Ensure you have received all exhaust parts and tunes before uninstalling any parts from your truck.
2. Tune Before Installing Exhaust or EGR Delete Kit: Always tune your truck prior to installing exhaust parts or the EGR delete kit to avoid complications.

Warranty and Return Policy:

• No Returns/Refunds: Due to the VIN-specific nature of the HP tuner and ECM custom tuning, returns and refunds are not available.
• Lifetime Warranty: All pipes, exhaust systems, EGR kits, and non-electronic parts come with a standard lifetime non-prorated warranty.
• One-Year Warranty: Tuners, tuning software, and electronic parts are covered by a one-year manufacturer warranty.

Cab Chassis Truck Compatibility: For Cab Chassis trucks, we recommend selecting the 4-inch exhaust or delete pipe with a downpipe for correct fitment without the need for modifications.

Tuning Options:

• No Transmission Tuning Included by Default: Transmission tuning is available as an option. If selected, you will need to send your TCM stock file for custom tuning. We’ll guide you through the process to ensure everything goes smoothly.

EGR Delete Kit: Remove harmful gasses and soot that cause build-up and performance loss. Our EGR delete kits reduce turbo lag, lower engine temperatures, decrease weight, and clean up your engine bay, ensuring a longer-lasting, better-running truck.

DPF/DEF Exhaust Systems: Choose between a DPF race pipe or a full 4 or 5-inch exhaust system that entirely replaces your old exhaust and removes DPF emissions components. This exhaust is designed to work seamlessly with our custom tuning.

About the Exhaust Systems: We offer exhaust systems from top brands like Flo~Pro and MBRP, ensuring you receive high-quality components tailored to your vehicle. These systems are constructed for durability and performance, with features like lap-joint style clamps to maintain pipe integrity and stainless steel components for longevity.
