Hello. I've owned a few RC cars for a while now and I just bought my first plane. It is a [link=http://www2.towerhobbies.com/cgi-bin/WTI0001P?&I=LXEKF346]Hobbico Superstar[/link] and comes with an O.S. .40LA engine. The muffler on this thing is much different from what I'm used to (i.e.: HPI Savage, Duratrax Evader). It seems like it's going to rob me of power. Are there any aftermarket mufflers that would be a better choice? I've looked around on TH and I found this [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXNB20&P=7]Slimline Pitts Muffler[/link]. It's still much different from a RC car's tuned pipe, but appears less restrictive than the stock .40LA muffler.
