Gbauer, you are running the exact kind of exhaust system that I am talking about. I think that you are right, at least for the street. Do you think that you have gained power with split exhaust even if it dumps into 1 pipe in about 2' or so? I think that it would be less restrictive than a single 2.5 inch pipe comming off say a 292 manifold . It would be cool to know how what you gain. For myself, I am going to go one of 2 ways: 1. A single 2.5 inch pipe hooked up to the one bbl manifold all the way back to a super turbo muffler for a Camaro. 2.5 single in twin 2.5 out. When I put on the 2bbl manifold I would run 2 " pipes for a short distance and hook up to the single pipe. OR 2. Run the Z28 twin pipes with twin mufflers and tails. Use the Y pipe to hook to the single pipe for now and run 2 2 inch pipes to the mufflers when I go with the 2bbl manifold. I am leaning toward the single pipe. Thanks again for the replies and advice. Jay 6155
