Pro Circuit exhaust quiet insert wanted.

[Mark D]

Hi, I wonder if anyone could point me in the right direction. I am looking for a quiet insert for my Pro Circuit T4s pipe on my DR650.
This slip on is very loud and the deceleration popping can get embarrassing at times. These inserts are available mostly in the USA on line, but for what it is, it works out quite expensive.
It would be great if I could get one from our local dealers.

Thanks, Mark.
