I thought the stock SESG pipes were pretty lame until I rode a stock Soft Tail Deluxe. Even with the 103 motor, the softtail was like riding a toy. The screamin' eagle mufflers on the SESG are much better than the non-CVO bikes. At least I could hear a muffled whimper when I gunned the stock CVO mufflers.
The final straw was when I stopped in a super market parking lot to let an elderly gentleman slowly cross in front of me. Half way across the crosswalk, he looked up at me with a surprised look on his face and said "I'm sorry. I didn't know you were waiting, couldn't hear you". I ordered my Bassanis later that day.
