Resonated Catless Test Pipes for 350z VQ35DE

The Circuit Werks Resonated Catless Test Pipes are designed for the 2003-2006 Nissan 350z with the VQ35DE engine. These pipes feature a resonated design to help manage exhaust sound, smooth exhaust flow, and reduce drone, while also providing performance gains.

Constructed from stainless steel, they have a 2.5" outer diameter and a 2.25" inner diameter. Integrated flex pipes absorb engine movement, and they are a direct bolt-on replacement for the factory catalytic converter. O2 sensor extenders are included for installation. These test pipes are intended for off-road use only and may not pass emissions in certain states.
