I had the sport version with the connecting pipes. Connecting pipes came free with the mufflers. It fit together perfectly and install was very easy, I did it myself on my back in my garage. For me it was too loud inside the car especially at slow speeds. At slow speed the drone was quite annoying and the bass would just resonate throughout the cabin. Some people like that though. From outside it sounded very nice though. Not obnoxiously loud, but quite a bit louder than stock. Had a very deep sound. But I chose to take them off and sell them a week after installing them. Not the sound I wanted, to much like driving a racecar all day.
