G37/370Z VQPlug ART Pipes | Stainless Steel Resonated Test Pipes VQ37VHR

The VQPlug Resonated Test Pipes are built for those who want the sound and flow of straight test pipes — but with significantly less drone. Made from TIG-welded 304 stainless steel and equipped with an integrated quarter-wave resonator, these deliver true performance gains without sacrificing comfort during daily driving.

Each pipe uses a side-branch quarter-wave resonator chamber that’s tuned specifically for the frequencies that cause interior drone on the VQ37VHR platform, specifically in the 3000RPM region. This design improves tone while keeping your cabin free of the harsh resonance that typically comes with test pipes — and it does so without adding any measurable back pressure.

Weighing in at 6 lbs 8 oz each, these pipes come in at less than half the weight of factory catalytic converters, while still offering OEM-level strength and reliability for track use.

 • Integrated quarter-wave resonator tuned for VQ37VHR 3-4k RPM frequencies
