    409S Stainless Steel. Designed with strength in mind, this muffler boasts a 16-gauge 409 stainless steel construction, which can easily stand up to the rigors of off road use. The American-made muffler is also fully MIG-welded, giving it unbeatable durability for long-lasting use.

    Warranty. If you have any concerns about the quality of this muffler's materials or craftsmanship, check out its limited lifetime warranty for details and limitations.
