VQ35HR Resonated Test Pipes

The VQPlug Resonated Test Pipes provide the sound and flow characteristics of straight test pipes while significantly reducing interior drone, making them ideal for daily driving. Constructed from precision TIG-welded 304 stainless steel, these pipes feature an integrated quarter-wave resonator specifically tuned to counter drone frequencies common in the VQ35HR platform, particularly in the 3000 RPM range. This design enhances exhaust tone without adding back pressure. Each pipe measures 2.5" in diameter and weighs 6 lbs 8 oz, offering a substantial weight savings over factory catalytic converters while maintaining OEM-level strength for track use. The pipes come with pre-installed O2 sensor bungs, allowing for the use of factory sensors in their original placement. Included with the test pipes are header side crush gaskets, Y-pipe side 2-bolt flange gaskets, and comprehensive mounting hardware. Compatibility is specific to the 2007-2008 Infiniti G35 Sedan and the 2007-2009 Nissan 350Z, both equipped with the VQ35HR engine. These resonated test pipes are engineered to reduce weight and increase exhaust flow without compromise, serving as a balanced upgrade for VQ35HR builds seeking improved performance and a more refined exhaust note.
