The Walker Exhaust 17758 is a high-quality 3" x 9" x 19" aluminized steel oval exhaust muffler designed to enhance vehicle performance and durability. Constructed from aluminized steel, this muffler offers superior resistance to corrosion, ensuring a longer service life compared to standard mufflers. Its three-tube internal design effectively reduces interior resonance, providing a quieter and more comfortable driving experience. The patented internal flow director technology channels exhaust flow efficiently, minimizing turbulence and optimizing performance. Additionally, the fiberglass matting technology dampens interior resonance, further contributing to a subdued sound profile. The large-diameter internal tubes improve exhaust flow and reduce back pressure, leading to increased horsepower and torque. This muffler is engineered to flow up to 700 SCFM, demonstrating its capacity to handle substantial exhaust volumes. Designed for easy installation, it features a direct-fit design with OE-style hangers, brackets, and pipe routings, eliminating the need for specialized fabrication or welding. This ensures a precise fit and reliable performance, making it a valuable component for fleet operations seeking to maintain vehicle efficiency and reduce maintenance costs.
