High-performance DPF-back exhaust system for enhanced power and efficiency.
The Advanced FLOW Engineering Exhaust System Kit is engineered for high performance, featuring a 4 Inch mandrel-bent 409 stainless steel construction that ensures maximum strength and durability. This system is designed to replace the factory exhaust with a DPF-back configuration, enhancing exhaust flow and reducing back pressure. The dual 5 Inch polished 304 stainless steel intercooled clamp-on exhaust tips provide a stylish finish while improving exhaust velocity.
This exhaust system utilizes factory-style hangers for a straightforward installation, mounting directly to factory locations without the need for welding. A mitered merge collector is incorporated to minimize turbulence, which contributes to increased horsepower, torque, and improved throttle response. The system is 100 percent MIG-welded, ensuring race-proven strength and longevity.
With a focus on performance and fitment, this exhaust system is designed using advanced computer-aided design technology, guaranteeing a custom, high-tolerance fit. The absence of a muffler allows for a more aggressive exhaust note while maintaining compliance with emissions standards. This kit is ideal for those looking to enhance their vehicle's exhaust system with a durable and efficient solution.
