After dragging my MK1A out of storage I'm going through the stuff I've bought for it over the years and haven't installed yet. Most of it around '93-95 and primarily from CAT, Sunbeam Specialities, and Dale A. I've got a set of club headers, these have the dumps on the side, obviously to allow for "uncorking" them. I notice the new headers offered by CAT come down to a single collector. I've also got a 2" exhaust system from Sunbeam Specialities. Any issues using these? I know with the passage of time, products that were once offered as "the thing to get" sometimes fall into the "what were they thinking" category. My engine is a stock 260 with the usual "289 2bl cheats" we all did to get around the techs in Solo II. At this point I'm not sold on using the headers, they've always been more of a PIA than a help on a stock motor on other applications I've used them on.
