I have the Vance and Hines Straight Shots. The quiet baffles increase back pressure which helps low end torque and they take the "tinny" harsh sound out while still being deep and loud.

I have the rush-slip on and you can change the baffles to make it louder or quiet. 2 1/2 would be the loudest and 1 1/2 would be quieter. Thats whats good about the rush slip-ons you can change baffles.

If you can afford it, check Eastern Perfomance for a good price on Reinhart True Duels. Sound good and run good.

The answer to your question is no, baffles don't make a bike louder. They are there to absorb sound waves and quiet things down. They have also been designed to improve performance at the same time. Removing the baffles on the Rineharts defeated the performance (sound and power) of the muffler. Quiet baffles don't really improve low end but they do reduce power (and sound) everywhere, around 3-5 hp/tq on a stock motor over the standard baffle. Rule of thumb is larger ID baffle equals larger noise and power.

Baffles quiet the pipes a bit and create back pressure for the scavenging of the exhaust which equals more torque and or horsepower for the vehicle. Removing the baffles will provide a louder sound but you will lose the scavenging properties of the exhaust. If you are looking for a deeper sound try the big city thunder baffles in your vance and hines. If you wnat it louder and do not care about low end torques thenm you cna take them out. It will be the equivalent of riding with drag pipes.
