Reccomended Cat-back Exhaust for my 99 2.5L?

Swapping out the TINY headers on your car for some nice aftermarket ones with larger pipes will actually register on the butt dyno. More power across the whole RPM range. Here's a dyno pull of what it did for my 2.5:

Dragonwind,

I recently added a Stebro Sport exhaust to my 986. So far I like it a lot.

RandallNeighbour's advice above is very good. My exhaust is noticeably louder in the cabin with the top up. With the top down the sound is either masked by wind noise or just doesn't resonate as much with the open top.

I'm really curious to hear what it sounds like with my hardtop installed.

Thanks again. What about for the CAT? Should I even bother replacing those when I put in headers and muffler? $ is the other issue and I have to budget accordingly.
Thanks
