Fitment Tips:

DPF/filter-back systems keep factory emissions equipment intact and are emissions-friendly upgrades.
Bed length/cab style matter (e.g., Mega Cab short bed vs. crew cab); choose the part number for your wheelbase.
4" systems are quieter and lighter; 5" offers a deeper tone and headroom for future power mods.

Frequently Asked Questions

Do DPF/filter-back systems add power?: They primarily reduce restriction and improve sound/appearance while retaining emissions equipment. Power gains are modest on stock trucks but they prep you for future upgrades.

4" vs. 5" — which should I choose?: Choose 4" for a milder tone and towing; 5" for a deeper note and more flow headroom. Stainless resists corrosion best; aluminized saves cost.

Will I need new clamps or gaskets?: We recommend fresh hardware during installs. Common items include the Mopar downpipe gasket and turbo outlet V-band clamp.

Are these parts emissions compliant?: DPF/filter-back systems retain factory emissions components. Always check your local laws and the product page notes for specific compliance information.
