OS 1.4 RX Header and Pipe installation in Focus II

[Robert Harden]

Thanks for the suggestion to use the ES or Aeroslave Pipe in the setup.  

Was wondering what the group experience shows is the best of these pipes with the OS 1.4 RX?  I would like to know the experiences in pipe length for each of these too.

  Bob,

  The standard OS pipe is on the heavy side: 5-6 oz.

  The ES and Aeroslave pipes are around 3 ozs and work very well on the OS 140.

    I would like some advise for installing a header and pipe in a Focus II.  I have the OS 1.4 RX engine, the OS 72102100  Header and the OS T-6010 Tuned Silencer.  My problem is that the header has interference with the firewall. I don't really want to remove material from the firewall to gain clearance.  Is there another header that I could use?  My other question is if the OS Tuned Silencer is the best choice?  I also would like to know what the length should be if the tuned silencer is used.  I am planning to use an APC 17 X 13 prop and Magnum # 1  2 cycle fuel (approx 23% nitro).  All suggestions are welcome.
