I have the new shape mondeo 2.5 V6 non SVT for which there is no aftermarket cat back exhaust.
I can put on headers and y pipe but I will still have 2.25 in piping from cat back, does anyone know if this will limit the horsepower?
I've done the heads as well and I'm puting in SVT cams.

YES, you will be limited unless you make a CUSTOM 2.5" exhaust. That's your next step. Think outside of the "pre-made box"

At what bhp will the 2,25in exhaust be a restriction, if that's a sensible question?

Seems like they get close to 190-200hp (wheels) and then start tapering off big time.

I wish Bassani made a 2.5" catback! I love the sound of mine, but wouldn't mind going a little larger. Maybe a true dual system w/ Bassani mufflers is in my future.  Mark

you could always just put a muffler in the resonator's spot and say screw the rest

So a 2.25" exhaust (if done right) should be plenty for my very lightly modded (non-svt) Duratec?

Correct. 2.25" mandrel piping has more then enough flow ability to support most 2.5L engines without restriction.

If you have to choose between two exhaust sizes that are "close" to ideal you are better off going with the smaller size. Velocity beats volume.

Never made a mondeo SVT but they did make a Mondeo ST200, which was the same. They don't make an ST200 mondeo in the new shape tho, so I have to!
