Thanks, It is a standard 1 1/4 inch FE endcap from the 550. (Seems close to 1 1/4). The endcap was 7/8 on the Doma can.
The exhaust does seem to make it through the Doma a little easier the way it is routed inside. And the can is lighter and sounds cool.
Looks cool too
So whether it ads more HP, maybe not too much , but for $109 at titanium silencer was worth it for the added bling.
