4.2L Exhaust Flange

If you're looking to make a custom header for that Jaguar 6 cylinder (4.2L), this 3/8" thick mild steel flange will do the job nicely as a starting point. The flanges are CNC cut to fit the 4.2L heads.

The one piece flange (not 2 pieces) will keep all the ports in alignment while you fabricate your header, making fitment easier then having to align two separate flanges and worry about twisting when doing the fab.
