Any one have any idea what I'm going to have to pay for an HMF full system. I'm getting the undertail, and the tire hugger, and this may sound stupid, but I really like the way the HMF looks with the undertail and hugger. Will it run the same as stock if I install it and do nothing elso; or, am I going to have to remap it. I've been riding for a long time but no experience with fuel injection mods. I have a ducati with the carbon cans, but all I had to do with that was change the chip. Anyhow, any input would be appreciated. I know there are always a lot of exhaust questions, but if I'm going to do something to the Busa I want it to both look and run at least the same or better. Also, I'd like to keep it fairly quiet. I always had loud bikes, but I really like my Busa with the stock quiet sound.
