Upgrade your exhaust system with the Invidia Test Pipe featuring a high-flow catalytic converter, designed specifically for VQ35DE engines. This performance component replaces the restrictive factory catalytic converter, allowing better exhaust flow, improved throttle response, and noticeable gains in horsepower and torque. 

Built from high-quality SUS304 stainless steel, it ensures durability, heat resistance, and long-lasting performance. The mandrel-bent piping design reduces backpressure and eliminates bottlenecks, helping your engine breathe more efficiently. 

Unlike fully catless pipes, this version includes a high-flow catalytic converter, giving you a balance between performance and emissions control while maintaining a deeper, more aggressive exhaust tone.
