Hi guys.
So it looks like my club is finally adopting a 94decible limit on our planes. I am wondering if the stock muffler is above 94. I know I am going to need to take the plane down to the field to get tested as there are many factors that contribute to noise. I would like to have a quiter plane anyway. So, any ideas on an aftermarket muffler that will for sure bring the noise below 94. I am concidering both a rap around pitts or a tuned pipe. Not sure what is the most economical.

Thanks
