Product Details
Borla has been a leader in performance exhaust for over 30 years, known for their high-quality stainless steel systems. This universal Turbo XL muffler is a great option for custom exhaust builds where you need a specific sound and flow characteristic. It uses a transverse flow design, originally developed for GM F-Body Camaros and Firebirds, which mounts parallel to the axle. This setup can help create a unique exhaust note and improve performance.
Built from T-304 austenitic stainless steel, this muffler is made to last and won't rust. The 100% welded construction ensures it's strong, and the free-flow design helps your engine breathe better, potentially leading to improved performance. Inside, high-temperature continuous-filament fiber acoustic material is used for effective sound control, giving you a better exhaust tone without being overly loud. The natural mill finish can be polished or brushed before installation to match your custom setup.
This muffler features a single 2.5-inch offset inlet and dual 2.5-inch offset outlets, with one outlet on the same end as the inlet and the second on the opposite end. Its reversible design offers flexibility during installation. If you plan to clamp it, you'll need band clamps like the Borla 18004. For welding, the un-notched necks are ready for that type of installation. It's made in the USA and backed by Borla's Million-Mile warranty.
