What is a better exhaust for a 06 crf250r to improve preformance? A FMF Factory 4.1C Carbon Dual System or a White Brothers Carbon Pro 2 System? pros and cons
I would not recommend the carbon to any one thats not going to replace the packing every 4 hours or 2 motos. Don't know if the others have the same maintenance, I like the titanium muffler.
