my preference is towards the shorties, but that is because I prefer a single exhaust - If I was to run duals then I may run long tubes. For who makes good ones - it depends on your setup. If you are running a manual tranny, then WH has the best shorties; if running an auto, I'd go with the WH for ease of istallation or the Ford Motorsports for less cost but they need a bit of inginuity for running the exhaust (they are very tight against the top of the passenger frame rail). For long tubes, I've heard good things about the Duffy long tubes, and I believe that both doug thorly and hooker make some good ones for the EB.
