Exhaust Manifold adapting?

[dodge68charger]

How Do I Adapt This To Fit To My Exhaust System. Never Seen This Style Setup Before. So used To Headers. The opening is 2" and Wanna Run 2.5 inch Exhaust. Thanks

The only way that I can think of is to find a 3-sided flange that mates up to that manifold end. My first guess would be to try an old-school muffler shop to see what they have. The flange probably only fits 2" pipe (maybe not?)... but you'd have to have a piece of flared pipe, likely 2" diameter, that would accept this flange. Then you just have a muffler shop "bump up" that 2" pipe to mate with your 2-1/2" exhaust. That manifold will definitely be the biggest restriction in your exhaust.
