Chevrolet LS1-LS6 Straight Lake Header Kit


Includes One Straight Lake Header Kit for the Chevrolet LS1, LS2, LS3, LS6, LS7 hot rod motor.  These flanges are cut with a CNC HD (High Definition) Plasma cutter out of 3/8” Pickled and Oiled (P&O) steel.  P&O material is hot rolled steel that has been dipped in acid to remove the mill scale and then a light coated lightly with oil.  The end result is less work to clean off the mill scale as needed with hot rolled mild steel.


Kit includes: 

1 pair – 30″ long steel megaphones (1-5/8″ inlet & 3-1/2″ outlet) – 4″ outlet available upon request

2 – 2″ OD, 0.065″ wall plain steel (not aluminized!) 70 degree mandrel bends

6 – 2″ OD, 0.065, 10″ long plain steel tubing

1 pair – 3/8″ thick exhaust flanges – specific motor application listed above

(photo is shown just for reference, contents listed above is actually what you will receive)


Ports designed to be used with 2” exhaust tubing.


These flanges are designed in CAD and are test fit to make sure proper fitment is achieved.
