Product Details
This Borla 401664 Specialty Muffler is a well-built, universal muffler designed for applications that need a longer body, like many trucks and SUVs. It features a 2.75-inch center inlet and outlet, a 6.75-inch diameter, and a 24-inch body length for a total of 29 inches overall. This is their "S-Type" offering, providing a distinct sound profile compared to their larger diameter, shorter body mufflers.
Constructed from T-304 austenitic stainless steel, this muffler is built to last and won't rust. The 100% welded construction ensures solid durability, and the free-flow design helps improve exhaust flow. Inside, high-temperature continuous-filament fiber acoustic material is used for effective sound control. The un-notched necks mean this muffler is intended for a weld-in installation, though it can be clamped using 3-inch wide band clamps. Its reversible design offers flexibility during installation, and the natural mill finish can be brushed or polished to your preference.
Because this is a universal muffler, it's a good option if you're looking to replace a damaged muffler or customize your exhaust system on a truck or similar vehicle. It's always a good idea to confirm the inlet and outlet sizes and overall dimensions will work for your specific setup before ordering.
