I just had the Buywitchdoctor's XC Muscle Baffle Mufflers installed and I'm extremely happy with them! On my VTX1800 I had Roadburners and ever since I've been fatigued by loud pipes and the drone, especially at highway speeds. My buddies have loud, very loud, Harleys, the kind that ignite car alarms as they pass and I definitely wanted to avoid that. But I did want something better than the stock pipes, which are just too quiet. The Muscle Baffle Mufflers rumble with just the right level of attitude without wearing on you. You can find them here. I don't have anything to do with Buywitchdoctors, other than being a very happy customer. Huge thumb up to a great product!
