If you have a Dr. D exhaust system on your R could you give me some advice. I am looking for an exhaust system that will provide low end gains for my 05 CRF250R, as I believe the CRF lacks in low end power compared to other thumpers I have ridden. Will the Dr. D system provide the low end gains I am looking for? The only reason I am contemplating a Dr. D system is because I can score one brand new for $260. So, how do you like your Dr. D exhaust? Any regrets on purchasing it? Anything you dont like about it?
