The Walker Exhaust 18177 is a universal SoundFX® exhaust muffler designed to enhance the performance and longevity of your vehicle's exhaust system. Constructed from 100% aluminized steel, this muffler offers superior corrosion resistance compared to low-carbon steel alternatives, ensuring a longer service life. The internal drainage system effectively reduces moisture buildup, further mitigating corrosion risks. Internal partitions and mechanically joined tubes allow expansion and contraction during temperature changes to minimize distortion, while spun-locked heads and OE-style spot welds provide stability and longer service life. The louvered tube design helps reduce radiated noise, delivering a factory-style sound quality that enhances the driving experience. The muffler's customizable design features expandable bushings for easy fitment, though installation may require specialized fabrication and/or welding. Designed and tested to extend muffler life, the Walker Exhaust 18177 is a reliable choice for maintaining optimal exhaust system performance.
