Saw your post showing UFO's exhaust system. I assume that you are doing the dyno tuning and map work for him. I'm pretty impressed with what he has been able to do in a short time. Will you be making a map with this same system usng the stock cans also? What kind of power gains can be expected from this system verses the 4-2-1. Ignore that asshole that had a problem with your burn out. I'm pretty sure he is a little mental!
