I am sorry I don't. But in my taste, it's too loud. Maybe, I will eventually change those two long mufflers and put one twin in /twin out regular muffler at one time. It's the acceleration that is loud. When it's at iddle or at cruising speed, it's quite ok.
It's just a matter of personnal taste. I like it very quiet from inside. But I do like the sound of muscle-car for sure...but maybe as an observer.
I also put sound deafening of a similar type as the very popular one _ the name escape me right now... must be all that aluminium...
