    Ole-T I did just that on my OBS truck. I copied the Tymar intake with some 4" diameter exhaust pipe and bought a Donaldson filter from my local Cat dealer. (the same filter Tymar uses).
    I also made my own 4" straight pipe exhaust. I bought the down pipe but from there I fabbed up the rest. Depending on what cab you have will determine how much straight pipe you will need. My 96 SC needed about 5', then I went to Advanced auto and bought a "over the axle" pipe for a 2000 F350. It comes 4" dia, and it fits nicely, all you need to do is bend the hangars to fit the OBS exhaust mounts. Cost was about $45 including tax/shipping. All in all I spent about $125 for a 4" straight pipe all the way back to the stock location.
    Today am not at my home computer so I can't post part numbers for you.
