Overview

The Berk Technology Resonated Test Pipes are an exhaust component designed for VQ35HR and VQ37VHR engines. Constructed from full 304 stainless steel with 60mm piping, these test pipes feature integrated Sebring resonators to help reduce rasp. They include soft crush graphite collector gaskets and a mechanical CEL fix.
Show original supplier description
The Berk Technology Resonated Test Pipes with CEL Fix (SKU BT1407-RES) are precision-engineered exhaust upgrades for Nissan 370Z, 350Z, and Infiniti G37, G35 models manufactured between 2007 and 2019. By minimizing backpressure, they allow the VQ35HR and VQ37VHR engines to breathe more freely, unlocking their full performance potential. The inclusion of resonators helps to refine the exhaust note, providing a sportier sound without excessive rasp or drone. A key feature of this product is the integrated Check Engine Light (CEL) Fix, which ensures that the modification does not trigger a warning light on your vehicle's dashboard. This provides seamless integration with the car's diagnostics system, offering a hassle-free installation and operation.
