370z ISR long tube headers

ISR Performance Long Tube Headers – Nissan 350Z 370Z / Infiniti G35 G37

The ISR Performance Long Tube headers for VQ are designed to replace your factory header and catalytic converter. These long tube headers are constructed with 304 brushes stainless steel and heavy duty flanges. Designed with a stepped primary, 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.

• 2x Stainless Steel Long Tube Headers
• 2x 2 bolt exhaust gaskets
• 2x Head to manifold gaskets
• 4x o2 sensor bung plugs
• 4x Exhaust Nuts
• 4x Exhaust Bolts

Because these eliminate the flange between the headers and cats, these fit both VQ35DE as well as VQ35HR & VQ37VHR. Our customers have reported that they fit AWD and RWD, 350Z through Q50, LHD and RHD, as long as they have a VQ.
