Product Details

Borla CrateMuffler SBC 283/327/350 2.25 inch Offset In/Out 14in x 4.35in x 9in Oval S-Type Muffler

Borla(r)'s CrateMuffler is the world's first muffler purpose-built to optimize the sound & power of crate and custom built motors. The mufflers are directional. The outlet can be identified by the mounting bracket welded to the endcap. The directional design provides custom sound, tuned for each engine family and will dramatically reduce, or eliminate drone on specified applications. Built from premium T-304 stainless steel, superior to T-400 series (such as 409), to give you the absolute best in performance and durability. Precision computer numerical control (CNC) manufacturing ensures an accurate fit and best of all, Borla(r) stands behind every CrateMuffler with a Million-Mile Warranty. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.
