Taken the plunge and going for a Spectra G

[gramey]

It is a Zimmerman made for the Spectra, I did have to shorten the header as they accidently sent me the header for the previous gasser model. It came with the teflon connector but they also do a flexibLe steel coupling which I shall order as the white plastic looks a bit naff.
The other Zimmerman pipe for this heli is like a huge dustbin hanging off the side of the engine. It's vulnerable to damage in the event of a crash, which I'm a bit prone to, so I went with this one. It's lovely and quiet and just my opinion it doesn't make the heli look lopside by having a huge exhaust on one side.
