Product Description

The Vibrant 1141 Ultra Quiet Resonator is a high-quality universal exhaust component designed for systems with a 2.50" diameter pipe. Constructed from T304 stainless steel, the 1141 uses a straight-through perforated core surrounded by premium sound-absorption materials and housed in a compact oval shell. It effectively reduces exhaust drone, rasp and harsh resonances while allowing strong exhaust flow for both naturally-aspirated and forced-induction applications.

Whether you're refining a custom exhaust system or replacing a resonator in a performance build, the 1141 provides a durable and efficient solution. Because it is universal, fitment is flexible but requires proper installation--either via welding or clamped into a matching 2.50" exhaust section. Ideal for enthusiasts looking to reduce unwanted sound artifacts without sacrificing performance.
