Quietest S/A insert for '03 YZF250 ?

Recommended Posts

I need to put a S/A- quiet core insert on my stock YZF exhaust and I want the QUIETEST one made. Is PMB the one to go with, or maybe Dr.D? Does anyone know what the stock exhaust puts out db wise? What does the FMF Q come in at? I don't really care if there is a little power loss, not an issue. I did do a search and couldn't find the answers I was looking for. Could use some input.... Thanks! :cry:

I've tried them all.

The Drd and the Promoto billet are about the same in sound and a little loss of snap.The Drd has a several different inserts to chose from...I chose the mid length.These are the best bang for buck deals.

The FMF Q gives a little (very little) more power than both above...but if you combine it with a sx Powerbomb header, you will get more lowend grunt.It will make your wallet lighter,too.

The stock muffler sound tested at about 100db.

All of the above tested below the 96 rule.

I don't have exact numbers....but I know stock YZF's are not passing sound tests at races and I am with the FMF set up.
