Looking at the posting I am finding lots of good information on exhaust systems but not much detail on noise levels (except Muzzy's are LOUD). I am looking at doing a few mod's to my 99 and would like some advice please. I want to lose the weight of the stock exhaust but I want to keep the noise down. I see that this requirement disqualifies the Muzzy. It also looks like a PC2 and a air box modification from the Motorhead are in-order. Any advice on these items (or any other) is much appreciated. Also, where to go for the best prices?
