This Flowtech header features CNC mandrel-bent primary tubes that provide consistent tubing diameters for smooth flow of the exhaust pulse and increase the cylinder scavenging of the exhaust to improve engine breathing. The primary tubes are constructed from heavy duty 16-gauge 409SS tubing for increased strength and durability. This header uses a 2.5" collector for maximum strength and exhaust flow and includes a welded-in collector merge spear to help control exhaust gas re-entry into the primary tubes. The header also features an extra thick flange for a leak-free seal and maximum strength.

Features:

  • CNC Mandrel-bent tubes provide consistent tubing diameters for smooth flow and increases the cylinder scavenging effect and improves engine breathing
  • Heavy duty 16-gauge 409SS tubing for increased strength and durability
  • 1-1/2” primary tubing diameter for increased exhaust flow, increasing performance and improved throttle response
  • 2.5” collector for maximum strength and exhaust flow
  • Extra thick header flange for a leak-free seal and maximum strength
  • Welded-in collector merge spear to control exhaust gas re-entry into primary tubes
