Borla CrateMuffler ATAK Performance Muffler - Ford Small Block 289 / 302 / 351W V8 (400835)
Give your custom build or classic muscle car an acoustic overhaul with the Borla CrateMuffler, the world's first muffler purpose-built and acoustically calibrated to optimize the distinct exhaust velocity and power profiles of crate and custom-built engines. This specific CrateMuffler is precisely tuned for the classic Ford Small Block V8 engine family, including the iconic 289, 302, and 351 Windsor (351W) configurations (excluding the modern Coyote 5.0L). Engineered with Borla's highest-volume ATAK (Acoustically Tuned Applied Kinetics) technology, it unleashes a race-inspired, high-decibel roar that delivers the distinctive, throatier "Sound of Power" respected by motoring enthusiasts everywhere, all while dramatically reducing or entirely eliminating interior cabin drone when used on the specified applications.
Crafted to withstand the high temperatures and acoustic pressures of upgraded street and track engines, this directional muffler features a 2.25-inch offset inlet and a 2.25-inch offset outlet configuration. The premium build is constructed entirely from top-tier, heavy-duty T-304 austenitic stainless steel, making it vastly superior to restrictive factory systems and lower-grade T-400 series alternatives (such as 409 stainless steel) in both raw exhaust velocity and corrosion resistance. The unit features a classic 4.35" x 9.10" oval body profile with a 14-inch case length and a 19-inch overall length. Designed with strict directional flow paths to optimize exhaust scavenging, the outlet end is easily identified by a heavy-duty mounting bracket welded directly to the endcap. Precision CNC manufactured for accurate fabrication, it is backed by Borla's iconic Million-Mile Warranty.
