My 991.2 S/X51 with SC and PSE is catless, and all the sounds it makes are awesome. That's the way I hear it, and that's what many others tell me. It's way more than noticeable with PSE turned on. Many Porsche folks have asked what I've done to make it sound so good, so it can't be bad.
I'm sure it would be even better with headers etc, but I'm satisfied. On a Mustang dyno pull, it measured 470 Hp, for a 20 Hp gain

It's working just like your stock exhaust. CS models with Non-PSE still has valves, they just open automatically at higher RPM. In Sport mode valves are open all the time if im not mistaken.
With PSE, the muffler is different and the button allows you to close or open valves as you please. The only benefit you will gain by getting the control kit is having valves open at low RPM in Normal mode. Because all other times valves will open automagicaly anyway.

Sound on this exhaust is really nice. Perfect rumble at idle, aggressive when you give it the beans, quiet when going easy. My wife would never even know it's changed as she never sees >3000 rpm!

Give me a ring any time at 4848836197. We’re always happy to help and point you in the right direction. For your reference, the system for the Non PSE S models would have come with a valve controller kit for you to install and control the valves. You can still install the exhaust, it will just be in the default open position until you run the valve controller kit.

im asking cuz when i get home i always open the valve to make it quieter but when i start the car it seems to be on closed valves most of the time which is super loud lol
I love the exhaust but it’s sometimes confusing to know when the valves are open or closed even while driving

Hi John, just curious. Is the exhaust going on closed valve by default when turning off the car?

As for the valves themselves...they are default OPEN via spring pressure. When the valves are open vacuum has to be pulled on the valves to override that spring pressure to close them by sending a signal to a vacuum solenoid to pull vacuum on the valves (by the PSE programming or our key fob buttons if you haven't synced the signals with your homelink). When you start the car the valves will be open until vacuum is built in the system, which can happen very quickly. Now, I had a customer of mine try something once. He turned the key into the power position without starting the car, he then hit the valves closed button on the key fob/homelink, and then started the car. Apparently when the car was turned on the signal was sent to the vacuum solenoid to pull vacuum on the valves, and while the engine cranked over it built enough vacuum to close the valves by the time it was running. Therefore, he started the car with valves closed. I haven't tried this before myself, but it's something you can try and it may work

Hi John, thank you very much for the clarification , yes my key fob is programmed in reverse then cuz locked button makes the exhaust loud & unlocked button makes it quiet.
I thought it was an installation error.![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)
And thank you for explaining the valve system. I can swear I closed the valve before shutting off the car but it always started very loud as an open valve.
I will now press the button to close the valve after starting the car cuz it’s too loud in the garage. Lol
