Product details

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 Ford Small Block 289/ 302 (Exc. Coyote 5.0L)/ 351W CID V8 & Big Block 390/ 427/ 428/ 460 CID V8 FE Serie engine families. The directional design provides the classic S-Type sound and will dramatically reduce, or eliminate drone on specified applications. Add resonator 400938 to attain the Touring sound. 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. CrateMuffler,Ford Small Block 289/302 (Exc.
