Kies Valve Controller Porsche 992.1 / 992.2 for 2020+ 911 Carrera & Turbo models (non-GT3)

This is the "exhaust system" everyone doesn't know they need. Unless you are going Stage 2 and need a high flow cat, this is all you need. It's loud when you want it to be and quiet too! Cold start decibels are 10-15 higher than stock, crackles are more pronounced in Sport, and the best part is you can be 100% stock with the click of a button. I highly recommend this one!

Easy install. Great sound! Loud when you want, stock when you need. Just buy it.

Works great
