Borla Universal Exhaust Resonator 2.75" Center Inlet / Center Outlet (401342)
Clean up your custom exhaust note and wipe out annoying rasp with the Borla Universal Exhaust Resonator. Built with a highly compact 5-inch round body, this specialty inline resonator is the ultimate solution for custom street builds, sport compacts, and truck applications dealing with tight clearance constraints under the chassis. It features a straight-through performance design that tames harsh, high-pitched frequencies without creating restrictive backpressure or restricting your engine's horsepower. Packed with continuous-filament fiber acoustic materials, it provides exceptional sound tuning and cleaner cabin comfort.
Engineered to withstand brutal undercar heat and vibrations, this heavy-duty sound control component features a 100% welded chassis crafted from premium T-304 stainless steel. The integrated notched necks are specifically optimized for a quick, straightforward clamp-on installation using standard 1-inch wide band style clamps, making it a great choice for DIY installers who want to avoid custom welding. Its fully reversible layout provides maximum mock-up flexibility during installation. Arriving in a raw natural mill finish that can be brushed or polished to perfection, this American-made unit comes backed for life by Borla's legendary Million-Mile Warranty.
