Actually, exhaust systems have shown to make quite a bit of power.
I think the most accurate statement would be that there have been pretty sizeable power differences (15+ hp?) demonstrated between different systems, but since the factory system is very good, it's hard to get meaningfully more power than stock out of an exhaust.
You can save weight and change the exhaust note with aftermarket exhausts, but there have not been any significant differences in power documented. In all of the stock/aftermarket exhaust comparison dyno charts I have seen, the difference is within the error of the machine, and usually there is no standardization of testing conditions.
Very nice tone, not loud at all {Well my car is loud now because of the TODA header}, very nice look and not expensive.

BTW: I also like the Fujitsubo exhaust {looks good and has nice power}. And you can never go wrong with Spugen, nice guy in Duc {ahhhvtec}, variety of exhaust design and they also make some power.
