Status: offline 		Hello,

I have an older Yellow Aircraft Zero that I am restoring (it was crashed) that has a Super Tiger 3000 in it. I am not sure what type of muffler I should get for it to be totally enclosed in the cowl, whether it be a Pitts, Inverted, stock etc. No mention of the type in the instructions and the guy at Yellow didnt seem to know..he just guessed it was a Pitts. Any help would be appreciated.

Thanks

The two downpipes from the muffler will go to flex pipes to duct the exhaust out of the cowling near the bottom.

I will checkout the B&B stuff too.

Thanks,

i'm building a Royal Zero, will be using a Leo37, currently the mount is stock so the engines upright, but as it's not finished i may chop the mount and use a plastic one it so IF i have to cut the cowl for the head you wont see it on the side or bottom.
Question is, how would you guys go about making a custom exhaust that fits in the cowl with scale outlets, i saw this pic in the current RCM&E of such a exhaust ( larger ). getting the gas to the exits isn't hard, just pipes out, but making it work propperly is, any ideas? rules of thumb ect, outlet pipe has same volume as the standard muff for example??
Thanks
