Stainless Bros SS304 3" Oval Muffler – Now Upgraded With High-Temp Ceramic Fiber Packing
Our Stainless Bros SS304 3" Oval Muffler has been redesigned for even better performance and heat control. Instead of traditional fiberglass, we now use SS Bros. HH ceramic fiber packing—a material engineered to withstand extreme temperatures while maintaining optimal sound absorption. Because ceramic fiber is firmer and less compressible, it results in a slightly louder, more pronounced exhaust note compared to fiberglass.
The oval body allows for a larger internal volume compared to a round muffler, giving you a deeper tone with reduced overall noise. Combined with its polished SS304 exterior, you get a refined “OEM+” appearance without sacrificing performance.
