New to the forum, new Formula owner. 252 1996, 454 EFI. Oldie but goodie. Seems to be missing check valves for lack of better term on the exhaust. I cant find much on the old inner webs about this system. Looking for replacing.

Thanks in advance.
 
i'll see if I can find a picture. Really they are just a stiff rubber material that was riveted in place. I would assume if you can find a similar material they would be rather easy to cut and make replacements.
 
Yes, that was my plan. Just making sure restricting was not a problem. Material seems to be a belting type industrial rubber.
Thanks.
