I'm looking in to a stage 1 upgrade and not sure whether to go with the Arlen Ness billet sucker stage 1 kit or the stage II kit. My main concern with the A/C is the fact that I hate the stock football and want something that will give me a little more leg room on the inside. For the exhaust I am undecided between the V&H softail true duels or the samson true duals. There is a pretty big difference in price (about 200 bucks) so i'm not sure what the difference between the two would be. I already went ahead and ordered the Dobeck EFI controller - thank you Dallas for the info. I guess i'm looking for opinions from people that are running the models above and could help me out with some of your experiences. I appreciate any feedback, Thank you.
