It may be manufacture by Termi, but I'm not sure. What I do know is that it is the same stainless steel exhaust system that is on the 848 and 1098, just with black walls to the cans. I don't believe the flow, cat, or anything is different about them. I just bought a 1098s stock system for my 848. should be in my hands tomorrow and I will be able to tell you with 100% confidence then if there are any differences.
