From my very limited knowledge of FD's, Racing Beat makes a better exhaust setup. Maybe an FD guru will chime in and give you their better opinion. :)

It depends on what exhaust tone you want(how loud the car is) and what you have done to the car. If you want a quite exhaust then get a racing beat twin tip exhaust. Also if you are getting rid of the catalytic converter and running a new mid pipe or resonated mid pipe then it is going to make the car louder. Just remember the three mod rule.

Go Racing Beat
 
Racing Beat all the way, flows beautifully and not too noisey but gives a distinctive high pitched note when under heavy acceleration. Brilliant!

3 mod rule?

Adding too many bolt-on mods can cause your boost level to rise and exceed the fuel system capability. The result is a lean condition that detonates and destroys your motor. The stock ECU does not monitor boost level to adjust it back down for you.

The 3 mod rule says that 3 flow mods (list includes intake, intercooler, downpipe, cat, and cat-back) will cause your boost to rise too much.

To be safe, install a boost controller and keep your boost regulated to 10psi. I would do that after the 2nd mod and before installing the 3rd.

I happen to think the racing beat is an excellent cat-back if you want a clean stockish look with reasonable noise levels and excellent performance. It's not the maximum performance cat-back available, but it's an awfully good improvement over stock and it doesn't look rice at all.
