[NSRCA-discussion] Hatori 822 or Central Header?

[Matthew Frederick]

I've actually seen one of the Central headers with the hatori pipe come apart at the joint where the pipe meets the fitting that mounts to the head. I think it's a great idea for saving weight, it just depends on how much you're willing to sacrifice in longevity to save that weight.

  Your mileage may vary - depends on how you connect the header to the pipe.  My O ring on my ProLine didn't seem to last long at all - the O ring on my Astral seems to last at least 50 flights or so.

    What kind of "mileage" is everyone getting out of the "O" ring?

      I will add that one needs to replace the O ring in the muffler on a regular basis otherwise it will cause a leak.

        Here's my experience with the Central Header and the Hatori short muffler (Hatori 821).  The Central header is lighter than the Hatori.  My header is braced to the engine with a metal strap and the muffler is mounted on a soft mount near the stinger.  The "O" in the pipe has formed a deep indention in the header and now the muffler has a loose fit and leaks oil.  Others may have a different mounting method as mine seems to be flawed due to the indention caused by the "O' ring.

        Guys,
         
        I'm debating which header to get.  I already have 822 headers.  The Central header is stated as being lighter, and also at larger diameter which should help the exhaust.  What are some pros/cons with each?  I've had good luck with the 822, but also had one break (which was easily reweldable due to its being steel.).  
         
        Thanks,
        Jim
