Well I doubt u'll get enough to actually feel but check out acura forums, and search there you should find people that have changed the exhaust and you can see which is the better setupWhat is the best way to find out the most performance exhust for my 04 acura tsx?
exhaust like catback or exhaust like headers? either way there is not much of a HP gain from either of those in and of themselves regularly. as you can see here http://tsx.acurazine.com/forums/showthre鈥?/a> this catback gave the tsx only a 3-4whp gain. on the otherhand here http://www.hondata.com/tuning_k24a2_tsx_鈥?/a> you can see that with the correct I/H/E set up the TSX can gain 20whp just from bolt ons.

OR here http://www.hondata.com/reflash_tsx.html you can see that a tsx can gain almost 25whp JUST from a reflash, which requires no change in hardware, just dyno tuning. if you want the cheapest and easiest way to make a little more HP: i would go with the reflash.
As others have said you will see little gains when upgrading the exhaust, assuming of course you are just doing at catback. If however you upgrade the headers as well you can see a large gain in the region of 20-25 horsepower as the K24 header is very restrictive,
