Most Akrapovics have the removable baffle, but I am not so sure the full system for LC4s does. Sommer KTM makes a db killer insert, it kills some low end power, but makes it much quieter. I would have concerns about traveling out of the first world with a ti exhaust, it requires a special inert gas rig to weld, so I assume repairs would be nigh impossible. It is an $880usd system that I have wanted for some time for my ADV but I have concerns that it will not clear the accelerator pump on my Keihin FCR-39 MX carb.
You may wish to check out Creepers LC4 exhaust thread at ADVrider.com he has been compiling the complete LC4 exhaust list for some time. At the same site KTIM has a write up on the Akrapovic and the Sommer db killer. Cheers, Mack
