Fast Intentions is proud to present our VQ37VHRHR Long Tube Headers. This is the world's first "production" long tube header for the VQ37VHR engine. The premier upgrade for all Infiniti owners looking maximize the performance output of their VQ37VHR naturally aspirated or supercharged engine. With the addition of these headers all restriction created by the OEM exhaust manifolds and catalytic converters will be eliminated. Built as a direct OEM replacement, our long tube headers bolt right in; no cutting or welding required. The 1-5/8" primary tubes are mandrel bent to maximize exhaust flow and efficiency. In addition, we've designed these headers to be firing order specific to maximize performance. This creates a rifling or tumbling effect. Proper exhaust scavenging is achieved, and turbulence is decreased. The addition of the FI long tube header is our LOUDEST option.


PRODUCT INFO

  • Direct OEM replacement: no cutting or welding required.
  • Firing order specific.
  • 1-5/8" T-304 mandrel bent stainless steel primary tubes.
  • 3 into 12.5" T-304 stainless steel merge collector.
  • J-Bend style O2 sensor anti fouler designed to keep that pesky CEL (Check Engine Light) off. Note: In rare instances an ECU recalibration/tune may be required to eliminate CEL (Check Engine Light.)
  • 3/8" thick mild steel flanges. All flanges are bright nickel plated to eliminate potential corrosion.
  • All flanges are welded on the inside, sanded down and port-n-polished for a smooth exhaust flow. This process greatly reduces exhaust turbulence at the flange connection points.
  • Optional high-temperature black ceramic coating available. Black ceramic coating can withstand heat up to 1600 Degrees Fahrenheit. We recommend this process for supercharged applications.
  • Limited 3-year warranty on all welds and craftsmanship.
  • Application Specific: 2009-2021 Nissan 370Z
  • Years 2012+ will require removal of 1 OEM coolant sub-line. We will supply a new "low profile" coolant line, which will provide adequate clearance for the driver side long tube header tubes.

  • Not compatible on Right Hand Drive vehicles.
  • Gaskets, hardware and installation instructions are included.
  • Hand built in the USA.
