G35/350Z VQPlug Ti-Phoon Pipes | Titanium Resonated Test Pipes VQ35DE

The VQPlug Ti-Phoon Pipes are the final word in test pipe design for the VQ35DE platform. Built from precision-formed titanium and engineered with a back pressure-free quarter-wave resonator, these test pipes are designed to increase exhaust flow while reducing unwanted in-cabin resonance.

Each unit is constructed with a quarter-wave resonated chamber tuned to counter drone frequencies common to the VQ35DE under light load and cruising conditions. The result is a cleaner, sharper exhaust note that retains volume and character — without introducing additional resonance at steady throttle. 

The VQPlug Ti-Phoon pipes weigh significantly less than comparable stainless steel units, weighing in at less than 6 pounds for the PAIR- all while offering the corrosion resistance, strength, and higher-pitched sound titanium is known for.
