Hi!

I'm about to start building a GP CAP 1/3 Matt chappman. Since this model needs a lots of modifications to house canisters, I will build it stock and go for pitts style mufflers. My question is which engine I should buy considering that pitts style mufflers will be my only option? I've been looking at 3W 106, DA100, ZDZ100NG or a MVVS116. Which of these engines are happiest when using a very restrictive muffler? Do they all have the same bolt pattern for the exhaust? I haven't been able to find any pitts style muffler at all for the MVVS116?
