Have any of you used an after market air filters on your bike. The only filters I have found are made by jhp and I have no experience with thier products. Do these filters offer a performance advantage over the dp filters that come with the Termi exhaust? Do you know of any other company that makes a high performance air filter for the 749/999 and what was your experience with them. The air filters I have probably perform as well as any other, but like every Ducati rider I could always use a little more.
