1-3/4" Shorty Headers, VQ37

The ISR Performance Shorty Headers are crafted from durable 304 brushed stainless steel with heavy-duty flanges, designed for enhanced engine performance. Featuring 1-3/4" primary tubes, these headers are optimized to preserve mid-range torque while contributing to significant top-end horsepower increases. These headers are specifically designed to provide clearance for the OEM coolant tube (or "oil cooler" line) on the driver's side of the block in later model VQ37 engines, ensuring a straightforward installation. O2 sensor bungs are strategically placed to accommodate factory sensors, simplifying integration into your existing exhaust system. Included with the headers 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 legal for use only in competition vehicles that may never be registered, licensed, or used on public streets or highways, or in other exempted vehicles.
