304 Stainless Steel Shorty Headers

The ISR Performance Shorty Headers are crafted to enhance the performance of the Nissan VQ35DE 350Z (2003-2006) and Infiniti G35 Coupe (2003-2007) and Sedan (2003-2006). Constructed from durable 304 brushed stainless steel with robust flanges, these headers are designed for a direct replacement of the factory exhaust manifolds. Featuring 1-3/4" primary tubes, these shorty headers are engineered to optimize engine breathing. The design aims to preserve essential mid-range torque while simultaneously unlocking improved top-end horsepower gains. Each header is equipped with O2 bungs, ensuring compatibility with your vehicle's factory O2 sensors for a seamless integration. Included in the package are two stainless steel shorty headers, two 3-bolt exhaust gaskets, two head-to-manifold gaskets, six exhaust nuts, and six exhaust bolts. Please note that these headers are legally intended for use in competition vehicles only and may not be registered, licensed, or used on public streets or highways.
