I’ve had my vac hose blocked off with a little metal bearing ball.
It’s been like that since June 05, the sound is awesome.
I prefer this method simply because there is no visible evidence.
The whole idea is to stop the vac from actuating the flaps.

What about not installing the PSE electronics at all and just putting on the PSE exhaust cans? If there are no electronics installed, wouldnt the system be on (LOUD) all the time? Is there any probelem with this?

Thanks,

Yes, I believe that is possible too.

I know when PSE came out for the 996 that the flap was closed by default (instead of open by default like it is now) so people (including my local dealership) would install it and break the flap out on the inside so it was always wide open. For the late 996's (I think) and 997's they added the switch so you could have it off and on, but on was a bit of misnomer since it doesn't fully open up for the full RPM range with the "recommended" installation.

Having the power there is handy if you want to tone it down which could be useful if you are driving near homes at night or in the wee hours of the morning.

I'm really confused - if the dealer can install PSE as an after delivery option without the electrical switch that means PSE is on all the time - why is this different than disconnecting the electrical connector on factory installed PSE and why do folks think this option may be damaging while disconnecting vacuum may not be.

To reply to the last post about my exhaust, I do not have dual chrome tips. They're the satin finish, which is why I always assumed that I do not have PSE. Is it possible to have PSE with the regular Carrera S satin tips?

Thanks,

post a pic of the rear of your car and we will tell you

if you car makes an amazing sound you have some type of after market exhaust - if its quiet or just not that noticeable - you have stock

If you bought the car new I would expect that you'd know if you had PSE just by the option list. If bought used, there are enough clues to determine if you have PSE. Based on your previous posts and your description of the tips, it appears you may have Sport Chrono Plus but not PSE. Somewhere in one of your manuals (maybe the maintenance book) there may be a list of options that came with the car. Look for the XLF code.

There are a couple of ways you can check if you have PSE. I have included a pic od OEM PSE mufflers. Please note that this is a engine with the X-51 package installed, so the engine looks a little different than most 997 engines. However, PSE is PSE whether it is with the X-51 package or not.

The first way is to check the exhaust tips. If you have PSE with the original OEM tips installed, the tips will be dual outlets on each side. The outward outlet will be larger than the inward outlet. However, the previous owner could have changed the tips.

The way to easily check if you have PSE is to look under the car and see if there are two pipes leading from the muffler to the tips Circled in red). If you have real "dual exhaust" pipes, then you have PSE. If you have only one pipe coming from the muffler to the tips, then you have stock (non-PSE) exhaust.

If you get under the car you may be able to see the vacuum valves (circled in yellow). If you can see the valves, you have PSE.

Thanks for taking the time to create the pic/diagram. Very helpful. I'll take a look tonight to figure it out. I'll feel like a fool if I don't have it, given that I love the sound!

Thanks again,
Jeremy

Rob, what do you meen "cause cel"? What is cel?

I agree but I know nothing about engines/mechanics etc. This was the original question I believe.

It seems that this thread has followed in the footsteps on many and gone Has anyone actually answered or addressed the original question? It is a compelling Q, since I too feel the same way, but blame it on the fact that I am usually feeling friskier when I depress that little SPORT button that came along with my wart.

CleanSlate

Exactly my point... thank you USC
GO TROJANS!

1. Does the Sport button make the car louder - YES, if you have PSE (assuming the cable is plugged, otherwise no), NO, if you don't.

2. The increased throttle response means that you'll use less effort to climb the range of RPM's, so you'll get into the sweet spot of the exhuast sound faster wheter you have PSE or not. This doesn't mean that the sport makes it louder, but you get to the loud range quicker.
