Just got my Needswings Single CAI today. It was in the box for approximately 5 minutes before I tore into it and installed it. Took my time and enjoyed it. Nice quality stuff and the install was easy. Too bad it's rainy and 32 deg here today, so I really couldn't play around any. Did get a chance to push it a little in third, sounds nice and feels like it has more pep. Plus, Rob at Needswings is a great guy to work with. Tune is next. I hope that Eurocharged will be offering a special on their tune sometime Spring/Summer.
