BOS Exhaust ?

[les049]

Has anyone had experience using / fitting the BOS rear can on a R1200 GS ?

Thanks guys I got a BOS rear carbon can from fleabay for a real good price and really pleased with the quality of the product. The sound it makes is very nice, not over the top !

Next on the List

The BOS decat headers are next on my list ! do you need any remapping to the system when they are fitted ?

That might depend on which year your bike is. '04 - '06 don't seem to present too much of a problem. '07 can run a bit lean, although mine ran fine for the time that I had a full Remus system fitted to it but there is a concern about longer term damage.

'08 onwards, I wouldn't dream of running a full system without running the bike on the dyno and having air/fuel ratios checked. At that point be prepared to buy one of the aftermarket devices which adjust the fuelling and to have the bike mapped on the dyno.

remus headers and bos carbon can just clocked 22,000 miles between my old gs and present gsa no probs.
