The Walker Exhaust 17674~WK Exhaust Muffler is engineered to provide reliable performance and durability for commercial and heavy-duty vehicles. Constructed from aluminized steel, this muffler offers enhanced corrosion resistance, extending its service life and reducing maintenance costs. The internal drainage system effectively minimizes moisture accumulation, further protecting against rust and deterioration. Designed with internal partitions and mechanically joined tubes, the muffler accommodates expansion and contraction due to temperature fluctuations, thereby reducing distortion and maintaining structural integrity. Spun-locked heads and OE-style spot welds contribute to the overall stability and longevity of the muffler. The louvered tube design ensures a factory-style sound quality, effectively reducing radiated noise compared to straight perforated tubes. This feature is particularly beneficial for operators seeking to maintain a consistent and professional vehicle acoustics. The muffler's dimensions—16 inches in length, 9.75 inches in width, and 4.25 inches in height—make it suitable for a variety of applications, offering flexibility in installation. Its universal design may require specialized fabrication or welding, providing a customizable solution to meet specific operational requirements. By integrating the Walker Exhaust 17674~WK Exhaust Muffler into your fleet, you can expect improved vehicle performance, reduced downtime, and enhanced operational efficiency.
