Bought my 2010 Spiced Rum FLHXSE new in Aug '09. Soon afterwards I added a pair of fairing lowers, but the heat on my right leg was so intense that I couldn't stand it. So I took the lowers off and stowed them in the garage. Fast forward two years and I'm now preparing for a trip to the North Carolina mountains and I'm thinking I sure would like to have the lowers on the bike in the cold weather. So, after putting 30,000 miles on the bike I finally decided to get rid of my Cat. This forum has been so very helpful. Reading what you guys have written on the subject of headers, slip-ons and baffles and your experiences and preferences has been eye opening. After speaking with Steve at Fullsac (who is friendly and super knowledgeable) I decided to purchase Fullsac's X-Pipe "B" and their 2.0” CVO Muffler Cores. I went with the SERT because my local HD dealer has much more experience with the Race Tuner than they do with the TTS. Picked my bike up yesterday. Dyno says 97 horsepower and 116 foot lbs of torque! A huge improvement! Last night I put over 100 miles on and the sound of the pipes is better than I hoped. A total stranger comlimented the sound. The bike's performance is noticably improved. The lowers are back on and while my leg temperature is on the warm side, it's an order of magnitude cooler than the "fire on my leg" feeling I had two years ago. So I'm a very happy guy and I'm looking forward to seeing the autumn leaves in the Carolinas. Thanks to you CVO Street Glide guys for making this site such a tremendous resource.
