Bolt on to a 2-1/2" cat-back?

I understand that this is a 2-1/4" diameter. But will this bolt up to a 2-1/2" cat-back or is there a spacer that will combine the two?

If you are already running a 2.5" catback, I would recommend staying with a 2.5" mid pipe so that you are not choking your exhaust flow with the smaller diameter pipe. If you're worried about emissions, our SVE H-pipe and high flow catalytic converter kit could be your answer. It's 2.5" diameter, will sound better and comes in at a lower price.
