4"/5" Downpipe-Back Exhaust DPF & Cat Delete Pipe

The SPELAB 4"/5" Downpipe-Back Exhaust is a performance-oriented DPF & Cat Delete Pipe specifically engineered for 2019-2025 Dodge Ram 2500/3500 models equipped with the 6.7L Diesel engine. Constructed from robust SUS409 stainless steel with a 2mm thickness, this system ensures long-lasting durability and resistance to heat. It is engineered for a direct fit, simplifying installation which can typically be completed in about 1 hour with basic hand tools. All necessary clamps, bolts, and hangers are included, though you may need to reuse some factory hardware. Options are available for either 4" or 5" diameter pipes, with choices for a race pipe or a full downpipe-back system, which can include a muffler or be muffler-delete. A significant benefit of this DPF delete pipe is the potential for improved fuel efficiency, with claims of gaining up to 4-6 miles per gallon depending on driving habits and setup. By reducing exhaust backpressure and increasing flow, the system also unlocks the potential for enhanced horsepower and torque. It also eliminates the need for regular DPF maintenance and the risk of DPF failure, which can lead to costly repairs. Important considerations for installation and operation include: a DPF delete capable tuner is required to prevent check engine lights and diagnostic trouble codes due to the removal of emissions sensors. This product is intended for off-road and race use only and will not pass emissions testing in regions where it is enforced. The fitment is for Crew Cab Short/Long Bed and Mega Cab models; it is not compatible with Cab & Chassis models. For 5" DP-back systems, regular cab trucks will require modifications for installation.
