ISR Performance Shorty Headers - Nissan VQ35HR VQ37VHR 350z 370z

These Shorty headers are constructed with 304 brushed stainless steel and heavy duty flanges. Designed with 1-3/4" primary tubes, these headers are built to retain as much mid range torque as possible while allowing for good top end horsepower gains as well. These headers are designed to clear the OEM coolant tube / "Oil cooler" line found on the USDM Driver side of the block on the later model VQ37 engines without issue.
