Borla Crate Mufflers

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.
