I have the pro moto billet insert which is similar.
It made the bottom end pull alittle stronger into the midrange and it revs out a little faster/farther.
Mine tested at 92.5 db. If you want a little more power and want to keep it quiet this is the way to go. If you want alot more power and alot more noise an aftermarket exhaust is the only way to go.
