Hey Corbett,
To be honest its hard to tell, it seems better on the top end and the sound is amazing. Low, deep rumble. But it's loud, much louder than I had hoped. Overall though I'm pleased. I would recommend this to anyone for the cost and the perfect fitment. Hot Seat also makes the pipes custom for your bike, meaning on order. It takes a bit more time but it's worth the wait for the cost.
