I had the Tor's on mine they sounded good but nothing like the Jardines I put the Jardines on and they really woke it up.
I thought it was quick befor now when I put the Jardines on and I first took it out for a ride I thought I was on a different bike and the sound is really nice at low speeds as well.
And when you take off heads turn to see what that was

it really has a nice bark to it with a nice rumble.
