Will a QRS Silencer fit onto Sport System Header

[1fourty1]

I currently have a full HMF Sport system for my YFZ. I went to the season opening WORCS race in Phoenix and they are serious about DB levels this year. The Sport System is not going to meet the 101db limit. Is it possible to fit a QRS System Silencer to the Sport full system head pipe I currently have?
If so, what sort of adjustments would you anticipate I will need to make in jetting?
Thanks for any input!!

The sport series for the yfz head pipe will work with the qrs pipe. They match up the same. As far as jetting it might be the same but you want to do a plug check to verify.

I placed the order today with my local shop, looking forward to testing the difference between the QRS vs Sport Series on the Track & Dyno :D
