ISR Performance Long Tube Headers For Nissan 350Z and G35 with VQ35 Engine

HEADERS ARE BACKORDERED. NEW PRE ORDERS WILL BE FILLED END MID TO LATE NOVEMBER 2021

 

The Nissan 350Z ISR Long Tube headers for VQ35DE/HR are designed to replace your factory headers and catalytic converter. These long tube headers are constructed with 304 brushed stainless steel and heavy duty flanges. Designed with 1 5/8" from head flange to stepped 1 3/4" primary runners, these headers are built to retain as much low and mid range torque as possible while allowing for good top end horsepower gains as well.

The innovative High Ground Clearance, "HGC" design places the collector in a position to maximize ground clearance without sacrificing performance.

Each header features 2 o2 bungs placed downstream of the collector so that you can utilize your factory upstream and downstream o2 sensors. The downstream o2 sensor bung utilizes a flow restrictor to help avoid CELs.

You will be required to extend your primary o2 sensor harness to meet the new location which is lower on the header. ISR Performance 02 Harness extensions

Isr headers

Took a while to get here, but the product is super clean with good welds. Excellent work haven't got the chance to put it on yet.
