Borla Universal Spitfire Boomers Performance 2.25-Inch Center Inlet to Dual 3-Inch DTM Style Tips Polished T-304 Stainless Steel Oval Muffler (40059)
Unlock ultimate exhaust flow and aggressive acoustic tuning with the Borla Universal Spitfire Boomers Performance Muffler. Masterfully engineered to meet the demanding requirements of high-horsepower track setups, race cars, import tuners, and customized street builds, this high-efficiency unit utilizes a 2.25-inch center inlet to striking dual 3-inch integrated round DTM style exhaust tips. At its mechanical core, this premium performance muffler breaks away from restrictive traditional baffle layouts by incorporating Borla’s cutting-edge straight-through internal geometry. This innovative layout features a high-velocity perforation core that optimizes gas flow and exhaust velocity, generating an excellent scavenger effect. This advanced aerodynamic design maximizes peak horsepower, expands torque delivery, and completely eliminates backpressure bottlenecks for optimized performance configurations.
The structural engineering of the Borla 40059 addresses long-term durability and installation problems beneath harsh track and street conditions through a 100% welded, heavy-gauge setup. Enclosed in a robust 5.5-inch by 8.5-inch oval by 14-inch long barrel case with a total 26.25-inch overall footprint, this robust assembly delivers excellent space optimization when tucked into narrow transmission tunnels, low-clearance chassis floors, or crowded under-car layouts. The specialized straight-through body layout packs a massive volume of advanced, high-temperature Continuous-Filament Fiber (CFF) acoustic sound control packing. This advanced insulation filters out high-frequency rasp and annoying highway cabin drone while preserving a raw, unrestrictive mechanical tone under full throttle. Built completely from fully polished, aircraft-quality, premium-grade T-304 austenitic stainless steel, this heavy-duty canister delivers an eye-popping, mirror-shine aesthetic straight out of the box. Utilizing a sleek, un-notched neck designed primarily for clean weld-in workshop configurations, this elite USA-made performance component delivers bulletproof structural stability backed by Borla’s legendary Million-Mile warranty.
Straight-Through Flow Dynamics & Space Optimization: Unlike basic factory replacements or restrictive multi-chambered mufflers that choke engine velocity, this Spitfire Boomers series unit features a high-flow straight-through network. The center-to-dual tip configuration allows you to line up straight-line piping routes inside tight factory channels, using precise internal perforation matrices to break down high-energy sound waves without placing a physical restriction in the path of the thermal gas exit.
Fabrication Installation Guideline Note: This high-performance universal muffler is built with smooth, un-notched attachment collars engineered explicitly for a permanent, clean weld-on installation. If your custom layout demands a slip-fit, clamp-on assembly instead of a permanent weld, it is highly recommended to utilize a heavy-duty, wide two-bolt style structural band clamp (clamps are not included) to guarantee a secure, leak-free exhaust connection.
