I replaced my FS570 stock muffler with a stock SX 250F unit.
The bike revs much better and runs cooler, the only con is the noise...
I was looking to buy the Doma 96db unit from bergos.de but the 250F can came in almost free...
i have just bought one doma full system from doma shop with power bomb but the power bomb faces down past bashplate now doma shop wants nothing to do with me anyone eles had this problem
hi there i have a doma system on my 650 and its great makes a big difference over the standard system and its sounds good also.
the only thing is the harder you ride it the faster it un packs itself
