Exhaust Downpipes/Test Pipes

The Flashark DP29773 is a high-performance exhaust downpipe and test pipe combination engineered for the Infiniti G37 (2008-2013, Coupe and Sedan) and Nissan 370Z (2009-2018) models equipped with the 3.7L VQ37VHR engine. Constructed from premium 16-gauge T-304 stainless steel, the DP29773 features computer-controlled mandrel bends for smooth, unrestricted flow and TIG-welded joints to prevent cracking. The CNC-machined flanges are chrome-plated for corrosion resistance and provide maximum strength and durability. The inlet and outlet diameters are both 2.50 inches, facilitating a significant increase in exhaust airflow. This product is intended for off-road and track use only, as removing catalytic converters will make the vehicle illegal for street use and will cause emissions-related check engine lights (P0420/P0430 codes). A tune is recommended to disable rear O2 monitoring and optimize performance. The kit includes two performance downpipes with pre-welded O2 sensor bungs, four high-temperature flange gaskets (two 3-bolt and two 2-bolt), and ten pieces of professional hardware for a complete bolt-on installation. Compatibility is confirmed for the 2008-2013 Infiniti G37 3.7L V6 (Coupe and Sedan) and all Infiniti Q50/Q60 models with a 3.7L engine. However, it does not fit 2.0 or 3.0t models. The product is also noted to fit the Nissan 370Z.
