Got a couple questions about my Great Planes Texan:

1. Can someone send me a link on where to buy/order a, I think its called, sport scale muffler for a .46 size engine? Im not sure if thats the right name, but its the one that comes out of the engine and goes straight down out of two pipes. None of my local shops have any.

2. I have the .46 Thunder Tiger, but I found a MDS .68 for 50% off at a local shop. Is the .68 worth going to, or would I be happy with the .46?? I havent heard too many good things about MDS.

Any help would be appreciated!
