I know that FRPP makes headers specifically for these heads. Will any other headers work? I just need a unequal length shorty or maybe a long tube if the price is good.
I know that MAC makes a set of P specific headers. Some people have success with some LT headers not sure which ones you might want to do a search and see. There are also a couple of good sites on the P heads that I have found by doing a search.
If you have time and aren't rushed ebay is a great place to find motorsport P headers for a bargain. I paid 180 for my ceramic coated FRPP headers.
