They upgraded the exhaust for the '05s, but on the '02-04s its still a bit of a bottleneck. I personally really like the RS*R ExMag, it's very quiet, has a nice deep tone when you get on it, a sweet looking exhaust tip, and full stainless construction. It's a bit too much of a sleeper for some, but for me, it's the perfect upgrade if you're only planning on doing some basic mods (like intake & header). If you think you might do a heavy N/A build-up or eventually go turbo, it's probably not the right exhaust for you.
