Description

The Flowmaster FlowFX Extreme Single Exhaust System is described as the "peak of exhaust enhancement." It offers "truculent exhaust reverb" (aggressive tone) and claims to improve fuel efficiency. It also "brushes up" the engine's capabilities, particularly in sustained speed and torque power. The system utilizes mandrel-bent stainless steel tubes, known for heat-dispersing and rust-resistant qualities, making them ideal for long-term use.
