Reply to "Are big bore headers big enough ?"

dm (Guest)

When I bought my heads from CHI (I have the 218cc versions) John told me go with 2 inch header primary tubes and 3" for collectors and mufflers. Smaller would be restrictive. The Pantera has its fitment limits and off the shelf headers fitting that dimension dont exist (or didnt a few years ago). Your stock muffs wont work well at all. I'm not saying you cant drive it that way, its just you wont get the maximum potential results. PPC headers or PI headers are close without going custom made. Send the Hall units back. I sold my Halls and got PI big throat. They work pretty good. (No Dyno numbers)
