Just picked up a 06 LT-R450 with a full rossier system.

It's possibly the loudest pipe I have ever heard!

Has anyone else got a Rossier system?

What do you think of it?

Has anyone had experience with the Rossier wiet core thing?

Iv'e got a Rossier on both my ltr's. I love that pipe. Rossier is also a great place to work with.

Are you guys using the quiet cores? How much power do they sap? I think I may be better putting the standard pipe back on.

believe it or not, the supertrapp endcap is supposed to add almost .5 extra hp. I have it sitting in my garage. I just dont like the way it sounds and i dont like how it makes the silencer really hot. I put it on for when I need to make a sound clearance.
