The old muffler I had on my ASP 91FS engine was starting look like it had seen better days, so I though i'd get this from HK as its much cheaper than elsewhere. Mounted it to engine and works a treat.... just like it should !!! Thanks a lot HK!

i have bougt this muffler 60 days ago, now afther 10 flight i'm not happy anymore.I have lost the end part of the muffler in mid air....the end part is not welded to the muffler like a OS or saito muffler...

so it looks good but you will certainly have problems afther a couple times flight.....
