High-performance axle-back system with optimized exhaust flow control.
The Advanced FLOW Engineering Exhaust System Kit is designed to enhance vehicle performance through its innovative axle-back configuration. This system features a factory-style exhaust valve that utilizes the original exhaust valve motors, allowing for precise regulation of exhaust gas flow based on throttle position. Constructed from 3 inch to 2-1/2 inch mandrel-bent 304 stainless steel tubing, it ensures maximum strength and durability while resisting corrosion.
This exhaust system is engineered without a muffler, producing a mild sound that complements the vehicle's performance without being overly aggressive. The high-flow design is complemented by dual 4 inch diameter black stainless steel clamp-on exhaust tips, which are finished with a rolled edge and laser-etched logo for a distinctive appearance. The system is 100 percent MIG-welded, providing race-proven strength and reliability.
Installation is straightforward, requiring no welding and including all necessary hardware. With an estimated installation time of just two hours, this exhaust system is a practical choice for those looking to enhance their vehicle's exhaust performance and aesthetics.
