Hi all, i'm new to the way of the Subaru.

does depend if they are after market exhausts on the size. But generally should be fine but I would check both sizes 1st to make sure.

And welcome to S.O.C  

Welcome to the club.

Only issue I can think of is if they relocated the hangers on the back box.

It's a ninja 11 back box. 2 1/2" pipe

Wotcha and welcome

As long as the rest of the pipe work is the same it should fit fine ( famous last words ) :D
