There is a catalytic converter in the very front of the muffler. It is about 3" long and about that in diameter.
Biggest obstruction is the end tube on the muffler. The internal baffling is a perforated core with packing surround.
Overall looks like a very nice design for maximum flow.

Sounds like I won't be having to build my own exhaust to make me happy. Most manufacturers today know how to tune an exhaust for a single cylinder engine to match other components selected as a set to provide certain power characteristics. That is why engines of the same displacement can have such wildly different outputs. 250cc engines available today range from 12 to 45 horsepower, some with flat torque from just off idle to 10,000+rpm, some that won't pull a bike at less than 7,000rpm. Exhaust tuning is a HUGE part in the overall formula for each bike.
