Trouble with the 600SS it was the only bike in the range with a 2 into 1 and unlike the 600 Monster they stopped making it 3 years earlier so less of them about. Same goes for the tanks and many have been rusting out


As for price, they do come along cheaper but are few and far between.
going to a 750SS or 900SS system will probably cost you somwhere in the same region if not more

As you need
Exhaust Down Pipes
Colletts
Exhaust Flanges
Left Hand silencer (and possibly matching right one)
