I too am a fairly new Z owner. I did a lot of research into exhaust as my 2019 Z was just too quiet. To make a long story short I bought and installed a pair of stainless mufflers from Top Speed Company. I have had them on for over a month now. They went on easy using car ramps to get the car up. Nissan left adjustment so you can get the tips fairly even, centered and at least 1/2 to 3/4" down from the plastic valance. Just have some patience to get them looking good. As far as sound, the are NOT overpowering at all. At idle very slight rumble, when accelerating they really sound the part. Highway at 50 MPH, 60, 70 and 75 MPH just the right exhaust note with NO DRONE. You can have a real conversation over the exhaust note. Cost $299.00 delivered to my door in just a few days. Good quality, great sound. Hot Rod Z
