    Cross-pipe repair.

    The cross-pipe on my 450 has rusted through and I've now got a hole that's about half an inch wide. Would any of these exhaust repair kits do the job or do I have to take it to a shop to be welded? Thanks in advance.

    Just weld a cap over the holes. I never understood a need for the crossover. No crossover makes removal and installation much easier too.

    I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

      The Suzuki crossover pipes are the first to rust out,imo. They're very vulnerable to road fling and moisture under there....

      As a quick fix, funky, not guaranteed but has worked well enough for me,
      You can try "hvac foil tape". Several makes, commonly available,but check it out here at 3M.
      When sealing ducts and other surfaces for heating, ventilation and air conditioning systems (HVAC), it's essential to have a strong, long-lasting foil tape that can stand up well to hot and cold tempe


      It's high-temp to a certain degree... I've used on several crossovers and even on holes in a crankcase or valve cover temporarily....clean off as much rust as you possibly can and wrap it 'right round the pipe several times. A hose clamp can help back it up. I've even wrapped it on crossovers that aren't yet thrashed as a preventative measure...

      It's generally useful for several things...sticky but It does NOT stick to any oily surface.
