dB Performance Exhaust Systems

The exclusive patented RSC™ Muffler design delivers a bold, unique sound under throttle that defines your performance car, truck, or SUV on the open road. But inside, you experience the quite ride, where you can use your cell phone or listen to the radio. The patented RSC™ Muffler features a straight-through design that incorporates a full 360-degree air gap, sending targeted sound waves to specifically engineered channels. The waves are then returned to the gap 180 degrees out-of-phase, cancelling the specific "drone" creating frequencies. All that remains is the bold rumble that it the true voice of performance.

  • dB Performance Exhaust Mufflers

    dB Performance mufflers are made of 100% stainless steel and do not use cheap, easily degraded packing materials, which ensures your product will last. dB Performance relies on its roots in technology to eliminate the annoying interior drone often heard with other aftermarket exhaust systems. You can cruise down the highway without painful and annoying resonance, but still get the deep truck growl when accelerating or idling.The combination of stainless steel construction and the fact that our systems don't use cheap, easily degraded packing materials ensures your product will last.

Designed, engineered and manufactured in the USA with a 10-year Limited Warranty.

  • dB Performance Diesel Downpipes
