I plan on buying the exhaust on e bay to save some cash, but I was wondering what exhaust to get. I Have the stock exhaust on the bike and am wondering which one would be the best for my money. I see a lot of FMF exhaust and and I am wondering if that is a good exhaust for me. I do not want a quiet exhaust. Since I have a four stroke I wanted that deep prrrr that makes a man feel good in the morning. The bike is a YZ 250F 2001. By the way I want the exhaust to give me more power as well, I am not all fo show. I plan on spending no more than a little over $200. Please give me suggestions in any direction. Feedback is good. If i get this exhaust tell me if i am going to have to get a new header as well. And how long is it going to take me to change the exhaust. Thanks a lot guys, I tried looking for a thread on this and could not find one.
