Borla Universal Center/Dual Oval 2.5in In/Dual 2.5in Out 19in x 4in x 9.5in Notched PRO-XS Muffler

Borla is known for making some of the most respected exhaust systems out there, and their ProXS line offers a lot of that same quality at a more accessible price. This universal muffler, part number 400485, is a great option if you're building a custom exhaust system or replacing a worn-out muffler. It features a center inlet that's 2.5 inches in diameter, and it splits into two 2.5-inch outlets, making it ideal for setups that go from a single exhaust pipe to dual pipes.

What's really handy about this muffler is its reversible design, which gives you more flexibility when figuring out the best way to route your exhaust. The notched necks are a smart touch, making it easier to get a secure clamp-on installation without needing to weld right away. It's constructed from high-quality T-304 austenitic stainless steel, so you don't have to worry about rust, and the 100% welded build means it's strong. Inside, it uses a free-flow design with continuous-filament fiber material to manage sound, aiming for an improved performance note without being overly loud.

This muffler has a natural mill finish, so you can polish it up or leave it as is before installation. It's made in the USA and comes with Borla's Million-Mile warranty, which really speaks to how well-built it is. While it's a universal part, it's designed to fit a wide range of domestic and import cars and trucks, especially if you're looking to create a dual exhaust system.
