Q.Pulsar 220F Exhaust- What's the difference?

[USER="15357"]Ashim_Ghost[/USER] As far as I know, the 2017 Pulsar 220F comes with only one type of exhaust. The old 220F had a steel one whereas the new, 2017 Pulsar 220F comes with blacked-out exhaust. The new bike is BS IV compliant and there might be some changes in the internals to comply with the norms. But the black colour is just for visual purposes. Performance wise, both the bikes are more or less the same.

I have seen two types of silencers in 2017 Pulsar 220f. I want to know the difference between them. Sorry for bad English.
