aFe uses an equal length single loop design on these Twisted Steel downpipes to help reduce drone and improve low end torque. It utilizes a 400 CPSI (cell per square inch) catalytic converter for maximum flow and mounts directly to your Raptor's factory mounting locations and includes hardware for a hassle-free installation. The downpipes are MIG-Welded by certified craftsmen for race-proven strength and durability and are constructed using superior-quality 3" mandrel-bent, brushed 304 stainless steel tubing for maximum performance, corrosion resistance and strength eliminating cracking.

Features and Benefits:
- Provides power gains up to +16 HP and +19 lbs. x ft. torque
- Includes "equal length loop" design for optimum performance
- Includes high-flow 400 cell catalytic converters
- 100% MIG-Welded by hand for superior strength

aFe intended these downpipes to be a "Race Only" product that are intended to be used solely for competition. Its use is limited to closed-course and open-course racing that is formally sanctioned by a recognized racing organization. Any other use including recreational off-road use could be in violation of local, state and federal laws.
