Headers and side pipes for 1969
I have a 1969, 472, with original side pipes. ( squere ports )
I understand I loose a lot of HP with original pipes.
I want to keep the side cowers.
I have looked at 2-1/8 inch tubes in headers and 3.5 or 4 inch. pipes from Stahl.
Is there anybody who have experience with that firm / type ?
Do I need Baffles ( from STS ) ?
What about the sound.
I look forward for some answers.

The snow are leeving Norway soon .
