Full Exhaust System - It sounds GREAT! IMO, it is the right amount of sound under load and cruising. Of course the slight backpressure burble is in there as well. I don’t know why anyone would drop 1K or more on another system. It’s difficult to stop driving because it sounds so glorious!

981 Exhaust System w/ Sound Valves - This exhaust is on my 981 Cayman S and it blows my mind. One of the best of exhausts i have ever owned on any of my cars. Jeff S.

 It is one of the best exhausts I've ever heard. Speedtech nailed it with this one. It's very exotic sounding and plenty of snap, crackle and pop! Steve B.
