Remus Exhaust

Has anyone replaced the R12GS exhaust with a Remus Exhaust? What about replacing the cat? If replacing the cat do you have to reprogram the computer chip?

I have the Remus cat eliminator on my '04 1150 with stock silencer...it works very well, seems to breathe easier etc and offers a nice dulcet tone too. On a GS it's hard to notice extra power although it does seem to have a little more grunt down low, maybe psychological although overall it was worth it. The weight savings are impressive too and it looks like a motorcycle again now. If you still want to run closed loop there is a take-off plug for the O2 sensor in the Remus. I can't comment on the silencer from Remus, as I like the stock looks somewhat better.
