Exhaust for 2003 YZ450F

I recently purchased a 2003 YZ450F, I love it. The time has come to upgrade the exhaust. I've read a ton of articles, but there isn't a clear cut favorite for this bike. The three I'm considering are: Big Gun, Dubach and Pro Circuit. I need honest opinions and arguements for you choice. I want to get this decided before this weekend, so I need everyone's help ASAP.

Thanks in advance.....


I live in San Diego and do a ton of dessert riding with some track......

Pick up the march issue of dirt rider, it has all the dyno #s and fit and finish ratings on each exhaust. The Dubach was a good one, especialy for a slip on. 49.4 peak hp, was almost as good as the best complete systems.
