<DIV><FONT face=Arial>Hi Fausto,</FONT></DIV>
<DIV><FONT face=Arial>The Mac's header is of very good quality and I've been
using them on my 140RX for the last 3 years. I've never had one break. However,
the diameter of the outlet is bigger on the Mac's header. The Mac's is 7/8"
(.875) and the OS is 3/4" (.75). Hope this helps.</FONT></DIV>

Pipe.</DIV>
<DIV><BR></DIV>
<P>Hi,</P>
<P>I've had a crash a while ago and damaged the OS exhaust header and tuned
pipe for the 140 RX. </P>
<P>I was checking at Tower Hobbies and found out that Macs also sells a header
for that engine at a much more reasonable price (<A

<P>My question is: The dimensions betewen the OS and Macs header's are the
same (primordialy the height from the engines exhaust port to the top of the
straight part of the tube).</P>
<P>The other option that I've seen advertised, at a more reasonable price
thans OS, is for the Hatori header and pipe. Any comments?</P>
<P>Any other comments regarding the quality, durability, etc for the Macs
header will be appreciated.</P>
<P>Thanks in advance,</P>
