    Great Value. Love the sound

    I had someone install these axle backs. They were a little tricky to get fit correctly working off jack stands. I suspect that it would be a much easier task on a lift. Once installed I loved the sound right from the first moment I heard them. They have a nice burble at an idle and they are not obnoxious in normal driving. I have not noticed any drone inside the car. However, they can really roar when you stand on it. I like these exhaust a lot.
