BORLA PERFORMANCE 400838 Features:
Borla'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-controlled CNC manufacturing ensures an accurate fit and best of all, Borla 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.A Muffler Specifically for Your Small Block Crate Engine
Borla crate mufflers are a unique, newly designed muffler specifically engineered for use with both stock and heavily modified Small-Block crate engines. Borla crate mufflers are a specially engineered straight-thru muffler that provides as much exhaust flow and performance as a straight pipe while providing the smooth sound that you desire. Borla crate mufflers are directional mufflers, and the flow direction can be easily identified by the mounting bracket welded to the end cap on the outlet side.
