Customer Questions

Question:

Are the runners equal or unequal length? - Frankie Urso

Answer:

Hi Frankie, they aren't 100% equal length due to external constraints that are in the way such as steering column, coolant lines, access to hardware, etc, but the runner lengths are fairly close to being equal.

Question:

Currently own a 2017 Nismo 370Z. I was wondering are these direct bolt? is the flange a DE or HR? I was looking at Z1's headers and noticed they are using de flange. not trying to swap my current test pipe set up for DE pipes. - Don

Answer:

Hi Don, these use an HR flange. The only thing you might encounter is most 2012+ models moved a couple of the studs on the cylinder heads, but they still have the holes, so you just move them to the correct locations to match the headers.

Question:

When installed on a vq35hr 07 Z, do they put pressure against the steering shaft? Had a bad experience with some cheap aftermarket headers and had to re install the factory ones due to the driver side header landing right next to the steering shaft and making it hard to turn the wheel. - Aris

Answer:

Hi Aris, we have never received any reports of these interfering with the steering shaft on any model

Description

ISR Performance Shorty Headers - VQ35HR VQ37VHR- Nissan 350Z Z33 Nissan 370Z Z34

These Shorty headers are constructed with 304 brushed stainless steel and heavy duty flanges.

These headers are designed to clear the OEM coolant tube / "Oil cooler" line found on the USDM Driver side of the block on the later model VQ37 engines without issue.

Each header features o2 bungs placed so that you can utilize your factory o2 sensors.

What’s Included:
  • 2x Stainless Steel Shorty Headers
  • 2x 3 bolt exhaust gaskets
  • 2x Head to manifold gaskets
  • 6x Exhaust Nuts
  • 6x Exhaust Bolts
