Flowtech 11585FLT - Upright Headers

Flowtech Upright Headers

GM 2.8/3.1/3.4L V6, Round Port Upright Headers 1-1/2" Primary, 20" Long, 27" tall, 2-1/2" x 10" Collector - 409SS Natural Finish

These Flowtech upright derby style headers fit the 2.8L, 3.1L and 3.4L GM V6 engines with both round port or D-port style exhaust ports. 1-1/2 in. and 1-5/8 in. mandrel bent primary tubes provide consistent tubing diameters for smooth flow of the exhaust pulses and increase the cylinder scavenging of the exhaust to improve engine breathing. The headers are constructed from heavy duty 16-gauge 409 stainless steel tubing for increased strength and durability. These headers use a 10 in. long, 2.5 in. collector with 20 in. long primary tubes. The 3/8 in. thick header flange provides a leak-free seal and maximizes strength.
