Man I love that muffler. It bolts right up to an irvine 53 and 46fx. This thing makes you think you have a totally different engine. You are right though, they are very loud.

I can tell you that the Tower 46 without the baffle is way too loud for our field, especially with the recommended break in prop.
The high pitched whine is extremely annoying, even from 50 to 60 feet away.
