Vibrant Performance – ULTRA QUIET Resonator 2” Inlet – 1138

Vibrant ULTRA QUIET Resonator 2” – 1138 is designed for those who want effective exhaust noise reduction without restricting exhaust flow in a performance setup. This model is frequently used in professional exhaust fabrication where both sound control and performance are critical.

The Ultra Quiet series is known for its ability to significantly reduce resonance and low-frequency cabin drone. This type of noise typically occurs under steady load and at specific RPM ranges – often during motorway cruising in top gear – where exhaust frequencies create unwanted cabin resonance.

The result is a deeper, more controlled exhaust tone without the monotonous booming sound that many performance exhaust systems can develop.

The resonator is constructed from premium 304 stainless steel and features a polished mirror finish. The material ensures excellent resistance to heat and corrosion as well as long service life for both street and motorsport use.

The compact construction makes it suitable for both custom builds and existing 2” systems where effective noise reduction is required without significant flow restriction.
