somehow I think they are OE BMW for the HP2? i saw some on ebay... they are £600 new apparently and the seller is flogging them seperately as he sold the bike with the OE stainless steel ones..
all a bit spooky really so just want to see if its all real...
There is a pic - they look the job, but they also look to be having a slightly fatter 2in1 section underneath, as if they contain a catalyst. Not as fat as the standard one though... In which case of course I am not gaining anything other than looks...
