I am looking to upgrade my exhaust as well as air filter and jet. I rode my other stock foreman and noticed how much torque and throttle response I lost when I added the modifications to my other bike (see my sig). Which exhaust is gonna give me the most HP back? I could care less if it was loud or quite. I just want more power back. Also who has the best price on what you would recommend? It seems hard to find an exhaust for an 2005 Foreman. Thanks in advance for your help guys!
