I just had a PSE put on my 2013 991 Carrera S Cab and have to say I'm totally underwhelmed by the sound, its not very loud, the difference to the stock exhaust or when the button is not selected is subtle, with the major difference being a bit of crackling on the over run. Any thoughts here? Will it get better as it is run in? I think they only changed out the center muffler, not the side ones.

Any thoughts much are welcome, I should have wen with TUBI!

 

It's night and day on my C4S.

Wonder what's up with your install.

 

to me ... my conversion was not a lot louder but was a whole bunch deeper sound ... which is what I wanted... if you really want louder there are some options to get you there from center muffler elimination to a different exhaust....

 

Do you have Sport/Sport Plus buttons?

On my car those deepen/louden the sound quite a bit, especially Plus.

 

Something is wrong with yours.

 

Agree

 

If you want loud, check out Sharkwerks side pipes that replace side mufflers on the CS. Pretty fricken incredible.

 

My C4S was very loud. Even got me a ticket. Very noticeable. Something sounds amiss.

 

+1...

 

Did you check the PSE valves? Are they opening properly when you press the button?

 

I've found this too. The increase in sound is noticeable to me though and the down shift pops and burbles are there. It's enough for me. C4S currently but with the soft top on my Boxster the change was very noticeable and almost too much for me if I left in on for long drives. Hope you figure out if something is wrong with your install.

 

if you don't love pse then you MUST add a Fabspeed x-pipe or center delete..it will wake up your car -

 

THIS! I'm considering the same thing--Fabspeed X-pipe and delete the stock center muffler... need to see what others that have done have to say first.

 

Pse & awe.

 

But isn't the PSE the center muffler? So I would just be ditching what I put on?
