Description
This DPF-back exhaust system is constructed of 4" mandrel-bent 409 stainless steel tubing for maximum strength and durability. Finishing off this exhaust system are dual 5" diameter polished 304 stainless steel intercooled clamp-on exhaust tips. The tips features an aFe POWER logo plate riveted on for a unique style. Some cutting may be required, see instruction sheet for further information. Utilizing factory style hangers this system mounts directly to factory mounting locations for a hassle-free installation. A mitered merge collector is used to decrease turbulence and increase exhaust velocity resulting in increased horsepower, torque and improved throttle response. Utilizing state-of-the-art computer-aided design technology, this exhaust system is designed for custom, high tolerance factory fitment. 100% MIG-Welded for race-proven strength and durability.
