A sound comparison between a 70mm Berk High flow cat and a 70mm Test pipe
Other exhaust mods include a custom 70/63mm Exhaust with 2x mufflers and a Ballade Sports header.
I honestly could not feel any power loss when I went from a test pipe/decat to the high flow cat.
The HFC made the exhaust less raspy and eliminated the foul exhaust smell. The test pipe was slightly louder and more raspy. The foul smell was the reason for the change.
