R1100GS DominatorR exhaust.

Less than $OZ300 delivered from Poland to Oz. Pipe, muffler, fixings. Easy install, ridiculously light compared to the oem lump, the db killer is installed and the noise is different but not too LOUD, but not entirely quiet either. That's an opinion for individuals to decide I guess. At cruising speed it hums nicely, wind noise is much more obtrusive.
This 1994 bike now has has 12pt injectors and I've added an O2 sensor/lambda probe.
