I have the quiet core IDS2 on my XR-L and absolutely love it. I am running 8 or 9 disks in it (memory failing), and it's a little louder than stock, but not a "loud" bike by any stretch. Weighs a lot less than the stock one, and makes it sound more like a bike and less like my lawn tractor, with a modest increase in power and response. Also jetted to a 160 at sea level and works well. I would by another if I was to do it again.
Cheers,
Jon
No, mine was the early style. Sounds like the new quiet version is a good choice.Did you have the "Quiet Series" supertrapp? I got that one as I keep reading the race series is way too loud.
