    Marks 4-2 HP Gains?

    So I've been eyeballing exhausts and so far I like the looks and sound of the Marks performance 4-2 the best. It has a nice deep rumble and it doesn't seem deafening from what I've seen on the videos of it. What can I expect in terms of performance gains from these? How do they stack up...

    Marks or UFO?

    I picked up these headers and cans from another forum member. He wasnt sure what they were, maybe UFO or Marks. Can anyone identify them as there are no markings on the pipes. Are these considered 4-2-1 or 4-1? I painted some parts black as they had a little corrosion. And probably not...

    Morley's Muscle Jet Kit and Marks 4-2 Exhaust installed...Jet size for 2500 Ft elev?

    Hello folks, and Happy New Year! I've just installed Mark's stainless 4-2, 2" exhaust and the bike started running lean / lacked torque. Then installed Morley's Jet Kit with needles on 4th clip, Mains 160 (2300-2500 ft elev, 47 degrees outside) and I suspect it's running too rich. The...

I have to say a few things about buying exhaust. 1...
