The Borla resonator option for CrateMufflers is a compact, reversible straight-through resonator designed to reduce overall sound by about 2–3 dB(A) without degrading performance. Made from T-304 stainless steel with 100% welded construction and high-temperature acoustic fiber, it suits tight spaces and can be used in any system of matching diameter. The natural mill finish can be brushed or polished and the part is reversible for installation flexibility.
