ProXS 2.25" Offset Inlet / Center Outlet Oval Muffler

The Borla ProXS muffler (Part # 40357) is a universal exhaust component designed for installation flexibility. Its reversible nature and un-notched necks are specifically intended for weld-in applications, though wide, 2-bolt band clamps can also be used for installation (clamps not included). Crafted from premium T-304 austenitic stainless steel, this muffler provides exceptional durability and resistance to corrosion. The 100% welded construction ensures robust strength, while the free-flow design is engineered to enhance exhaust performance. Internally, it features high-temperature continuous-filament fiber (CFF) acoustic material to manage sound levels effectively. The muffler boasts an oval shape with case dimensions of 14" x 4" x 9.5" and an overall length of 19", with a 2.25" offset inlet and a 2.25" center outlet. Borla backs this ProXS muffler with a Million-Mile warranty and proudly manufactures it in the USA. It's noted for providing a deep, noticeable sound without being overly aggressive, and is considered a free-flow design that can contribute to improved performance and potentially fuel economy.
