Product Details

The APR Premium Helmholtz Resonator is an engineered solution for eliminating exhaust drone and unwanted frequencies in high-performance exhaust systems. This precision-crafted component uses Helmholtz resonance technology to cancel specific sound frequencies without restricting exhaust flow, delivering a refined exhaust note while maintaining optimal performance.

Premium Construction Features:

  • T304 stainless steel construction for superior corrosion resistance and durability
  • TIG-welded throughout for maximum strength and leak-free performance
  • Brushed finish with stamped APR logo for a premium appearance
  • Rolled external structural ridges provide rigidity and distinctive styling
  • Unrestrictive straight-through design maintains exhaust flow and performance

Specifications:

  • Inlet/Outlet Diameter: 76mm (3 inches) with offset configuration
  • External Dimensions: 311mm x 240mm x 110mm (12.24" x 9.45" x 4.33")
  • Rounded square body design for efficient packaging

This Helmholtz resonator installs inline with your exhaust system to target and eliminate specific drone frequencies that occur during cruising or under load. The straight-through design ensures no power loss while effectively canceling undesirable cabin resonance, making long drives more comfortable without sacrificing the aggressive sound character of a performance exhaust.
