Racing exhaust for Mazda RX-8?

What's a good exhaust for a Mazda RX-8 that sounds good and gives performance gains? Doesn't have to be road legal or pass MOT. Recommended website?

Thanks

Answer:
You will find that Mazda did a very good job in designing the exhaust for the RX8, so the HP gains from aftermarket units are minimal. Dyno-testing of real installations and reported to http://www.rx8club.com have only shown gains around 3 - 5 HP. Do NOT believe the hype some manufacturers state that theirs gets 20 HP…it doesn't happen.

Some of the good ones that give you a nice deep, throaty sound are Mazdaspeed, Borla, and Racing Beat.
