Have noticed for several years mostly favorable comments concerning the Fullsac performance conversions on HD stock mufflers. Then a couple of months ago on another site, a fullsac dealer mentioned how good a donor muffler the 07 CVO's make. Since they are 4" and have a 1/4 in insulation around the outer core, they have a real nice mellow tone compared to the standard bagger muffler. Well, being one to try different mufflers, I scored a set of 07 CVO take offs to send to Steve at Fullsac. Turnaround time was 8 days and he does an excellent job. Only a very slight color difference on the bottom front of the mufler where the new baffle is welded. Not noticable at all when mounted. I love the look of these mufflers, and now I love the sound also. He replaces the stock baffle/cat with a 2" louvered baffle that is about mid level in terms of decibels. For comparaisons sake, they are much quieter than my V&H classics and about the same as my 4" Bassanni HO's, but to me, have a better tone due to the insulation. I've ridden about 200 miles since I put these on ( rain, rain, rain) and am very pleased. Excellent sound and again, I love the look. You also lose the inner portion that sticks out inside the tip.
When I talked to Steve on the phone, there was a little doubt about the difference between the 06 and the 07 CVO muffler. When I recieved the 07's from a member here, I compared them to my 06's, and could find no difference in the appearance internally. The part number is the same also. The only thing that I could find that would indicate that these mufflers came off an 07 was that under the part number, it lists the 1800 motor, and on my 06's, it only mentions the 1690 motor. So, most likely, the mufflers are identical, it's just that fullsac hadn't done any 06's and he couldn't comfirm that they would work. Just an FYI for any of you that like the look of your stock RK or EG CVO mufflers and want better sound, I certainly recommend the fullsac conversion. Wish I could do a picture, but my dial up is just too slow. Cost is $199, plus your shipping. Beats having them sit on the shelf.
