4" over tail recommendations?

[69ls1]

I am looking at the 4" over street tails for my busa. Which tail is of better quality or better fitment, the Airtech or Catalyst? Or is there any other brands recommended? Does anybody have any pics of a 4" over tail with a 6" extended swingarm?

Thanks.

Fairclough,

How much over stock is your swingarm? Is it a 4 inch over tail?

Thanks.

Swingarm goes 7.5" over, and yes that was a 4" over Catalyst tail.
