Borla Universal Exhaust Resonator 3" Center Inlet / Center Outlet (401339)
Eliminate harsh exhaust rasp and fine-tune your custom system with the Borla Universal Exhaust Resonator. Featuring a highly compact 5-inch round body, this specialty inline resonator is the ideal choice for high-performance builds, custom trucks, and street cars where space under the chassis is limited. Its straight-through free-flow performance engineering cleans up aggressive exhaust frequencies and tones down unwanted cabin resonance without restricting flow or holding back your vehicle's horsepower and torque capabilities. Packed with premium continuous-filament fiber acoustic materials, it provides precise sound attenuation while maintaining a deep tone.
Built to handle extreme track and street conditions, this heavy-duty sound control component features a 100% welded assembly made entirely from premium T-304 stainless steel. The smooth, un-notched necks are specifically designed for a seamless weld-in installation by custom fabricators, but they can also be adapted with heavy-duty wide two-bolt style band clamps. Its smart, fully reversible layout gives you complete versatility during system mockup. Finished in a raw natural mill look that can be brushed or polished to match your custom exhaust setup, this premium American-made part is backed for life by Borla's legendary Million-Mile Warranty.
