A vehicle exhaust system includes an exhaust component having an outer surface and an inner surface that defines an internal exhaust component cavity. At least one bleed hole is formed in the exhaust component to reduce a resonance frequency. The bleed hole comprises a discontinuous opening into the exhaust component cavity.
