NeXuS Mufflers are manufactured from 16 gauge 304 stainless steel. Our mufflers produce a unique and distinctive sound that is the result of merging two of the most popular muffler designs (glass pack and chambered) into one muffler. Beautiful sounding with performance that is better than the normally configured chambered muffler. With a deep, mellow tone at idle and cruise and a W.O.T. sound that won’t disappoint. Add our 90 day no hassle return policy plus our limited lifetime warranty and free shipping and you can see that NeXuS Mufflers deliver.
