Have a silver 2009 M109R and love it!! Time to install some Bling on it so I have a few questions....1. Where is the best place to install a Stebel compact air horn. 2. Best air flow kit Barrons, Ness big Sucker, air flow. 3. With the increased air flow which is best Cobra FI2000 or Power Commander 3. Thanks for your guidance I really appreciate it!
