A combo question... What would have a reasonable cool sound, without going to wild and perhaps have some hp to boot.

Stock exhaust + 200 cell cats Versus a Porsche PSE with factory cats ?

The last is what I have now, I wonder if my 12 year old cats now start causing either performance loss, or if they even would not last that much longer (I have '99 C2).

After reading numerous posts it seems the sportcats add serious sound, so imho a combo of pse and sportcats would be just to much.

Thanks in advance for any feedback !
