Why does a muffler need a warranty? If you bought a pile of crap muffler that is going to fall apart after a few years then you got what you paid for. Buy a name brand good muffler and you don't need a warranty especially when its going on something that is going to destroy it such as a wheeler.
Hence I bought a $40 flowy knockoff and if it falls apart before I put something else on there I won't be surprised..
