Stainless steel corrosion inhibition: Compared to aluminum-plated mufflers, the widely available mufflers with a stainless steel structure have a longer lifespan and reduced water accumulation due to internal drainage..Durability: Internal baffles and mechanical connecting pipes allow for expansion and contraction during temperature changes, minimizing deformation, providing stability, and increasing the lifespan..Working principle: The muffler wall is made of double-layer stainless steel, which helps reduce vibration and absorb sound..Installation: Exhaust mufflers generally have three installation methods that can be selected according to needs (1. Welding 2. U-bolts or muffler sealing clamps 15. Lap/joint clamps)..After-sales service: We value your shopping experience. If you encounter any problems during the installation of the muffler, you can contact us at any time through Amazon email.
