The 3.8 liter mufflers have a different part number (substantially different) - so I think even though they seem to look the same something might be different inside. But they look they could work.

The 3.8 engine also benefits from different headers - which I doubt would fit properly on a 996 3.4 liter either.

IMHO - if you are looking for horsepower I don't think you are going to get any.

I am actually to do exactly to do the same mod (for sound only) as you pointed me on RennList:

I want to make sure that I am hunting for the right 997 cans though!

I did exactly what you are doing I have a 3.6 and got some 3.8 mufflers for free so i decided to do the hack on those. They fit perfect and are exactly the same (the hack is one of the best mods I've done by the way) The only thing is that the 3.8 mufflers NEED the quad tips, the 3.6 tips are too small

On a 997S, I performed the following modification, as the one shown above does not work the same on newer cars - it isn't that loud when performed on 997 cans.

Here is a 997S can that I had a crossover piped welded into - the result is amazing, and it is nearly impossible to tell the difference between this and the PSE for $2000.
