The ISR Performance Long Tube headers for VQ35DE 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.
What’s in the Box:
- 2x Stainless Steel Long Tube Headers
- 2x 2 bolt exhaust gaskets

- 4x o2 sensor bung plugs

Are they fit on 2008 g35x
Hi Umid, these do not fit AWD
Will these long tube headers fit on the the vhr motor I have a 2013 rwd g37 sedan
Hi Joban, they have not confirmed fitment on VHR cars. The frame rails are slightly different between HR and VHR so unfortunately we can say for sure that they will fit and clear.
I have a 2007 hr, will I need the 02 extensions?
Hi Adam, the extensions will not work with the HR, so you would be better off just extending the harnesses on your sensors by way of cutting/splicing in longer wires.

Installed on my ‘05 g35 rev up, and dang these are awesome. Love the exhaust note, and power is there. Quality is truly there!
I put these on my 2013 G37S Sedan and they’re amazing. Welds are immaculate. The inside welds that bolt near the engine head where cleaned up very nicely. 0 Fitment issues. Fill fit any VQ37HR!!
Installed these on my 2018 370z and they woke the car up! I highly recommend installing at a shop if you do not have the confidence or the tools. Fitment was perfect and had no issues pairing this with my motordyne catback e370. Definitely felt an increase in power, went from art pipes to long tube headers which replaced them. For the price to power its worth it. In order for these to work on the 370z you must extend your primary afr sensor, i recommend nisformance for their extensions
