675 Aftermafket Exhaust For 10' Triple

Hi mates.

As I have read the most common plug and play aftermarket exhaust for the 2010 Street is the ARROW.

It indeed has an stock ECU remap available in the stores. Does it worth the bucks?

Been searching through eBay and don't manage to find those dual exhaust for my model. Where to find it?

Is the ECU remap for the silencers or for the whole exhaust system?

Thank you.

 

I see.

Is there any need of replacing the rest of the exhaust? Headpipes or so.

Any extra power gain with it?
