Hi all recently purchased a 2011 Deluxe. Wanted better exhaust sound but an ole guy so not wanting to lose any more of my hearing. Would also like a little performance increase if possible but not wanting to spend big bucks on performance. So, went to the dealer and having screamin eagle slip ons put on. Service guy said that I did not need to do the screamin eagle AC which with labor would run about $300. He said with the slip ons that also adding the AC I would not really notice any performance difference. He also said that if I did do the AC that I should do the "Race Tuner" which is about $700. I've read other places that just a "download" for about $150 would be all I would need not a Race Tuner. So what do you guys think 1.)should I ignore the Service guy recomendation and get the AC with the $150 download cause no way am I going to spend $700 on a Race Tuner. 2.) or just forget about the AC and enjoy a little better sound. Thanks for any help/suggestions and sorry about the long winded post.
