About this part

Product Details

What you get with this Borla Specialty Muffler is a well-built exhaust component designed for applications that need a longer body, like many trucks and SUVs. This particular muffler features a 3-inch center inlet and a 3-inch center outlet, with a 7.75-inch diameter and a 24-inch body length, bringing the total overall length to 29 inches. It's considered a "Touring" muffler, offering a more subdued sound compared to Borla's more aggressive options, and its un-notched necks mean it's intended for a weld-in installation.

This muffler is constructed from T-304 austenitic stainless steel, which means it won't rust, and the 100% welded build ensures it's strong. Inside, high-temperature continuous-filament fiber acoustic material helps manage sound for a comfortable driving experience. Because it's a universal part, it's designed to be reversible, giving you flexibility during installation. The natural mill finish can be polished or brushed before welding if you want to customize its look.

For installation, Borla recommends using 1-inch wide band style clamps, part number 18330, which are sold separately. If you're looking for a durable, USA-made muffler with a free-flow design for improved performance and a sound that won't be overbearing, this Borla unit is a solid option.
