The Walker Exhaust 18245 SoundFX Direct-Fit Exhaust Muffler is engineered to provide a precise fit and reliable performance for various Ford pickup models from 1987 to 1996, including the F100, F150, F250, and F350 series. Constructed from aluminized steel, this muffler offers enhanced corrosion resistance, ensuring longevity and durability in demanding operational environments. The muffler's design features an offset inlet and outlet configuration, each with a 2.25-inch inside diameter, facilitating straightforward installation and optimal exhaust flow. With a body height and width of 7 inches and a body length of 24 inches, the muffler's overall length is 29.25 inches, aligning with the specific dimensions required for these vehicle models. The SoundFX series is recognized for its factory-style sound quality, achieved through the use of louvered tubes that effectively reduce radiated noise compared to straight perforated tubes. This design not only maintains a quiet operation but also contributes to a more comfortable driving experience. The muffler's internal partitions and mechanically joined tubes allow for expansion and contraction during temperature fluctuations, minimizing distortion and enhancing structural integrity. Spun-locked heads and OE-style spot welds provide additional stability, contributing to a longer service life. Designed and tested to extend muffler life, the Walker Exhaust 18245 is a reliable choice for fleet operations seeking to maintain vehicle performance and reduce maintenance costs.
