    Pops & crackles are unreal! Great sound at cruise speed!

    I had them installed on my 2016 CTTS at a Porsche dealership yesterday. I have the factory sport exhaust. OMG, what a sound with exhaust button on! Pops and crackles are unreal on the downshift and deceleration. Great sound at cruise speed, too. Even a throaty growl with exhaust button off, but very pleasant. Clearly not an option for those looking for a quiet ride.
