<DIV><SPAN class=430233401-06052003><FONT face=Arial color=#0000ff size=2>Just a
point of clarification - the 480, 590 and 565 are mufflers only, not tuned
pipes, so comparing them to the ES pipe isn't really apples to apples. The
EQ140R would be a more appropriate comparison, as it is properly baffled for an
rpm boost. Different products for a different applications - the mufflers
were developed when popular opinion was that there was more than
enough power available in the 140 2Cs and that the boost wasn't needed.
Now that the current crop of F3A kits are getting HUGE, the tuned pipe
boost is back in vogue.</FONT></SPAN></DIV>

<DIV><SPAN class=430233401-06052003><FONT face=Arial color=#0000ff size=2>BTW,
we're working with the gent who posted about the Bolly pipes "leaking" and
"gaining weight" to sort out what's up. While they do "weep" for the first
few flights till the resin stabilizes, and they can be ruined if they get cooked
(as can all c/f pipes) it's the first we've heard of anything like this, so the
research continues. If any other Bolly pipe/muffler users have had this
problem, would you please contact me directly.</FONT></SPAN></DIV>

480, 590, and 565. The 565 worked the best on the ST2300. However,
each of these pipes was easily outperformed by the ES. The 3M carbon
pipe has the first baffle in the same location as the ES 2-cycle pipe I have
and it looks very similar in overall dimensions. If I remember
correctly, the first baffles of all the Bolly pipes were a lot closer to the
neck opening than the ES or 3M pipes. The 3M carbon pipe has an

note is similar to an Asano pipe I've heard run on Donny Wright's OS RX.
The Greve pipe has a longer first baffle dimension, so you'll need to run a
shorter header length to get the same tuning as the ES/OS type of pipes.
With the 17 x 13, you'll need all the power your can muster

a 2" difference in the 1st baffle position in the Bolly pipe to the
