Description

BORLA(r)'s CrateMuffler(r) 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. This muffler is tuned for the Chrysler/ Dodge/ Plymouth (Mopar) Big Block 396/ 402/ 427 CID V8 engine family. The directional design provides the aggressive ATAK(r) sound and will dramatically reduce, or eliminate drone on specified applications. Muffler dimensions 2.5" Offset Inlet/ 2.5" Offset Outlet, 4.35" x 9.10" Oval, 14" Long Body, 19" Overall Length. 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(r) with a Million-Mile Warranty. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.
