Powerflex Exhaust Mounts utilize the enhanced longevity, stiffness, and heat resistance of polyurethane to effectively secure your exhaust system. Key benefits include: - Reduced exhaust movement - Enhanced heat resistance - Improved longevity in adverse weather conditions Rubber exhaust mounts, like rubber suspension bushes, are susceptible to deterioration. The added challenge of heat from the exhaust system exacerbates this. As exhaust mounts wear, the exhaust system can experience increased flex. Combined with engine movement, this can lead to premature wear on exhaust components. Polyurethane offers a superior alternative due to its inherent stiffness, resistance to weathering, and high heat tolerance. Please note: Certain compounds are available in standard road compound and a harder black compound.
