Borla Universal Exhaust Resonator 2.75" Center Inlet / Center Outlet (401338)
Clean up your exhaust note and eliminate rasp with the Borla Universal Exhaust Resonator. Designed with a highly compact 5-inch round body, this specialty inline resonator is the ultimate solution for custom builds, trucks, and sport compacts facing tight clearance constraints or limited underbody space. It features a high-flowing, straight-through performance layout that tames harsh exhaust notes without creating restrictive backpressure or choking your engine's power output. Packed with advanced continuous-filament fiber acoustic materials, it provides exceptional sound tuning and cabin comfort.
Crafted to survive brutal undercar conditions, this durable sound-control unit features a 100% welded chassis made from premium T-304 stainless steel. The un-notched necks are specifically optimized for a smooth, seamless weld-in installation by custom fabricators, though it can also be paired with heavy-duty two-bolt style band clamps. Its fully reversible design ensures maximum mock-up flexibility during fabrication. Arriving in a raw natural mill finish that can be brushed or polished to perfection, this American-made component is backed for life by Borla's legendary Million-Mile Warranty.
