hello,

The only actual "out of the box" quad system I've seen are the Remus quad exhaust system and the Rieger exhaust (you'd need mtechII rear for it) Other than that, you'll have to go custom, with customized pipes without the muffler. This can cost up to 200 - 300 I would assume. Plenty of people have done this. Ive personally seen MixFlame's quad exhaust and it sounds great too!
