Gibson MWA Superflow Offset/Center Oval Muffler - 4x9x14in/2.25in Inlet/2.25in Outlet - Stainless

If you're looking to give your hot rod, car, truck, or SUV a more aggressive sound and improved performance, a new muffler is a great place to start. This Gibson MWA Superflow muffler is designed to make your exhaust system breathe easier. It features a straight-thru design that allows exhaust gases to flow at very high rates, nearly as well as a straight pipe, which can help unlock more power potential.

What sets this muffler apart is its internal design. It has no packing or weak baffles, which keeps it lightweight and contributes to its unique, powerful sound. This construction also means you won't have to worry about packing material breaking down over time. The muffler itself is made from quality stainless steel, built to last, and is constructed 100% in the USA. While it offers an aggressive exterior sound, the straight-thru design is also engineered to keep interior drone to a minimum, so your cabin stays comfortable.

This particular model is an oval-shaped muffler measuring 4x9x14 inches, with 2.25-inch inlet and outlet pipes. It's a non-directional, low-profile unit that fits right into many exhaust systems. If you're aiming for a noticeable change in sound and performance, this Gibson muffler is a solid option.
