When I installed the 2nd cat delete pipe and the Top Speed Muffler it definitely made a very noticeable difference in the responsiveness of the engine.

Power wise it feels like it helped as well. I would describe it as having more HP power earlier in the power curve.

The engine response seems instant now with little lag and by 4000rpm you feel getting pushed back in the seat with more force than before, whereas stock on the 2001 S you felt the power coming on strong more around 5000 rpm.

The result is that I'm certain the 0-60mph time is quicker since the power kicks in earlier than before.

I did the mod more for the sound, and it sounds great, but the overall result is much more than I expected and a nice surprise.
