Muffler change on Robin engine for PT 422

[MuncyBob]

My wife works 3rd shift and frequently is getting some of her sleep when I need to work with the PT near the house. Running the PT at full throttle is fairly loud when you are trying to catch some ZZZZZ's......was wondering if anybody has tried a different muffler to reduce some of the noise? /forums/images/graemlins/confused.gif
