Exhaust Choke Fix?

[Papele]

I have a EuroJet catless DP + Magnaflow CB

Both pipes are 3" but where they meet they become 2.5" creating a small choke.

If you catch my drift.

Does anyone know of a piece that is sold to fix this without welding? A sleeve of some kind maybe? I guess I could probably make a piece out of some extra piping though.

Perhaps a 3" electronic dump pipe I could fit in there?
