Fitment Information:
Nissan 350Z
Infiniti G35
(VQ35DE/VQ35HR engines only)
Customers have installed these on the 370z and G37 as indicated in the reviews below without issue as well.
Features:
The ISR Performance Long Tube headers for VQ35DE/HR are designed to replace your factory header. These long tube headers are constructed with 304 brushed 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 two o2 bungs placed downstream of the collector so that you can utilize your factory upstream and downstream o2 sensors.
You will be required to extend your primary o2 sensor harness to meet the new location which is lower on the header.
What’s in the Box:
Note: ***PLEASE INSPECT YOUR HARNESS PRIOR TO ORDERING AND ENSURE YOU HAVE THE EARLY MODEL VQ35DE 4 WIRE O2 SENSORS IN PLACE, THIS WILL NOT WORK WITH LATER MODEL 6 WIRE O2 SENSORS!***
** All ISR Performance Products are Designed for Off Road Use Only **

Nice
Took forever but such good quality
Packaging was perfect. not to much damage to the box. Seemed to come with everything that was listed. all in all- amazing headers so far and can’t wait to put them on my nissan 350z
Got these headers for my g37 and they fit perfect and still going strong 2+ years with no issues whatsoever. Delivery was fast and efficient.
If you’re looking for power in the low end and even more on the top end long tube headers is the way
Seriously. Best bang for your buck mod on these de z's. The long tubes bolted on with zero fitment issues. None at all. FITMENT WAS AMAZING. Will shift your power band to a higher rpm range, but you definitely feel the difference.
The rest of my exhaust is stock, but won't be forever. The tone is great, but I picked up a rattle from the oem mid pipe, not the long tubes fault.
Price for these is fantastic too. Can't find a better deal.
Seriously.
The product is very good, well worth the money I’m just experiencing a weird rattle noise coming from where the headers meet the Y pipe I mean it’s nothing to crazy but maybe isr should look into that but overall it’s been treating me well!
Excellent Service, Fast Shipping, Great Product Selection!!! I installed these ISR HEADERS on my 15' Q50, coupled with an ARK GRIP SYSTEM. SOUNDS GLORIOUS!!!
Fast & responsive, buy again
Fast shipping and great customer service. Fit my G37xs coupe pretty well
