Vibrant Ultra Quiet Resonator (3" Inlet & Outlet / 14" Long) Stainless 1142

The Vibrant Ultra Quiet 1142 is a 3-inch stainless exhaust resonator for custom systems that need to take the edge off exhaust noise, rasp, and drone.

Fitment Information

• Custom exhaust systems with 3-inch tubing
• Naturally aspirated and forced-induction applications

Fitment Note

This is a fabrication part, not a vehicle-specific bolt-on exhaust. It has a 3-inch inlet and 3-inch outlet, so confirm your tubing diameter, available installation space, exhaust routing, and preferred welding or clamping method before ordering.

Product Description

The Vibrant 1142 Ultra Quiet Resonator is for a custom 3-inch exhaust that sounds too sharp, raspy, or boomy on the highway. Its larger oval body provides more room for sound-absorption material than a typical small bottle-style resonator, while the straight-through perforated core keeps the exhaust path direct.

It is a practical choice for a street car with a straight-through exhaust, especially six-cylinder and V8 applications where rasp or cabin drone has become part of the setup. The 1142 uses T304 stainless construction and a compact 13.75-inch overall length, making it easier to fit into a custom mid-pipe or rear section where space is limited.

Before You Buy

Measure the available space before cutting your exhaust. The 13.75-inch overall length includes the inlet and outlet sections, while the oval body is 6.5 inches wide and 4.75 inches high. Final sound change depends on the engine, exhaust layout, catalytic converters, muffler, pipe length, and resonator placement.
