Header options

Why would I ever consider the Ireland Engineering headers. They are sexy looking but not that sexy

I have had headers & carbs on all my German cars. I just love that sound

@OCCoupe can tell you how tight they are to the frame rail.

i would buy the Stahl long tube design from ACP. 1.75" primary tubes require a real beast of an engine. i asked Ray Korman years ago about header size for the m30. his comment was that 1.5" was for something north of 250 hp and 1.75" was basically a race header. most stage 2 m30 engines did best on the dyno with the 1.375"
