SPDZ1 Long Tube Headers - VQ35DE/HR - Nissan 350Z Z33 370z / Infiniti G35 G37

The SPDZ1 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.


Each header features 2 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:

  • 2x Stainless Steel Long Tube Headers
  • 2x 2 bolt exhaust gaskets 
  • 2x Head to manifold gaskets
Fitment:
  • Nissan 350Z & Nissan 370Z
  • Infiniti G35 & G37
  • VQ35DE & VQ35HR Engines
  • Fits G37X (AWD) models

Specification:

  • 2.5" outer diameter exhaust collector
  • 1.8" outer diameter on the primary tubing
  • Direct bolt-on installation to OEM mid Y pipe
  • Flange is 3/8" thick
  • Includes gaskets & hardware

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

Came based on a work buddies recommendation. I was late by 30 minutes, confused my appointment time. But, 10/10 would come back. Came for a Downpipe and midpipe install. Not only was the gentleman accommodating, He ran into some issues, staff helped me out and pointed me into the right direction and got me going! They got my business and wouldn’t go anywhere else again!

Absolutely love the customer service that you get with Speedzone Performance! All my questions are always answered in such a timely manner and this a big PLUS because I live out of Florida and for them to be on top of answering all my questions in such a way means a lot. Thank you all for the amazing customer service.

My favorite place to go for anything car related, they have anything you could imagine & more. The people who work here are the coolest and most helpful people I’ve yet to meet at a car shop. They also don’t try to force sales on you and they genuinely help you with what you’re looking for, 100/10 shop!
