Description

The Borla ProXS muffler (part #400491) is a universal exhaust component engineered to deliver a deep, rumbling sound that is noticeable without being overly aggressive. This ProXS muffler features a 3-inch single offset inlet and a 3-inch single offset outlet, designed for clamp-on installation with notched necks. Its compact oval body measures 14 inches in length, 4 inches in height, and 9.5 inches in width, with an overall length of 19 inches. The reversible design provides flexibility during installation, allowing it to be mounted in either direction. While this is a universal part and does not have specific vehicle fitment data, its dimensions and connection types should be verified against your existing exhaust system for proper integration.
