Just an FYI on my my last post. I also had a great talk with Kieth at Fuel Moto. He explained that the "bark" or "crack" sound that you can get from the Rineharts is primarily due to the fact that the baffles have no packing at all. So he is sending some of the pro packing material that they use on their Jackpot muffler baffles. He also went over in detail exactly how to wrap the baffles for the best effect. Kieth claims that this mod should take away the "crack" and will porbably lower the exhaust note. Just what I'm looking for. Anyway, I'll do the deed as soon a I receive the material and then report back. If it doesn't get me to where I want to be, then I'll probably go with the Rush slip-ons and the 1.75 baffles.
Those that might be interested in installing the Rush mufflers onto the Rinehart TD head-pipes can see, and hear them, at rushracingproducts.com. They also have a huge selection of custom tips for a custom look. Anyway, just an FYI.
