I just got my Audiopipe in today and even the wife was impressed. I got the one that has Bazooka speakers and the 200watt amp(the Extreme version) and it absolutely rocks. I talked to the guy that builds them in Louisiana and he said that for the money, it would be best to buy the Extreme becuase at higher volumes the cheaper one doesn't have as good of sound clearity. I agree. I have now heard both and am glad that I spent the little bit extra. My wife said that she was glad I paid the extra $100 becuase she was very pleased with the results. Probably the best $325 I have spent on both bikes.
