Sport Exhaust on 2005 987

Steve, I had the dealership add the PSE to my 2006 987S (with Sport Chrono) last Spring. I love it. We did not install the on/off switch that can be intergrated with the SC. Sounds great in Sport (loud) mode at all times.

Check pricing with Sunset Porsche. They have better pricing than Suncoast. A dealership will want to charge at least 4 hours labor.

Why not integrate with the Sport Chrono?

The PSE is only easily integrateble with 2007 cars onwards. The necessary connection point in the engine bay is not present in pre 2007 cars.

I believe, however, that there has been at least one pre-2007 car seen with PSE integrated, however, it must have been done by installing a connection point back to the DME. This is outside the standard Porsche install/ TSB which only deals with 2007 installs with and without Sport's Chrono. I guess if you can find someone who knows exactly what they are doing the install must be possible on pre-2007 cars.

The install with or without integration is a reasonably easy DIY job if you are machanically minded.

Thanks, I suspected that. Now I am looking for the person that has done this, I would like to try it if it works with the 2005 software.

Does the PSE not increase the bhp given the fact that the RS60 is producing 303bhp? Does this car have any engine or ecu modifications that would indicate where the extra horses are coming from?

Porsche does not claim any HP gains from the PSE. The Sport Exhaust in the RS60 is not the same as this PSE.

The simple answer is you don't need to use the switch. It make the install less complex and less co$t. The exhaust sounds great. It is never loud, obnoxious or resonate. And you will crave the Sport sound even at low speeds and RPM's. If you intergrate it into the SC the sport mode (loud) function will not be activated until higher speeds, RPM's and throttle position.

I guess it's all down to personal preference. I find it useful to switch it off especially if I'm driving through a built up area/parking the car etc and sometimes I just want a bit of piece and quiet!

Guess it's down to you, but as White987S says non-integrated is going to make the install a good deal easier.

looking under the RS60 the rear silencers certainly look standard PSE items, the rear outlet is different as it has two distinct pipes linked to the cross over , rather than a single outlet with a dual trim. I suspect the increased power comes from revised headers and / or a modified ECU. Certainly 303 hp is easilly achievable from just an ECU reflash , even retaining the stock air filter.

Steve. I've just bought the PSE (with all the necessary wiring harness) for my 2006 Base Boxster w/out chrono or PASM. I'm told by Porsche in Queensland (thats like over 2000kms from me) that you can install it with on/off switch. However, no one local to me knows how to do it?!

I'm wondering if you found instructions anywhere?

Regards Henry

Henry, you really do NOT need the switch! Save the money and buy beer & gas!

Hmm but I really like the fact that i can switch it off.

Another question...so the PSE, is that somehow also linked to the DME?

A lot of questions Henry. seems like you have the same car as I have. A 2005 Boxster S. Mine with the PSE and a switch to select high or low mode. I have located it where the cig lighter used to be. No problem realy to do this fix. It is not possible to connect the muffler to the ECU on a 2005 model. - And I think this is a better way to controll the system. Now you can open up at idle - this you cant do on a 2007 model. I think you have to run in at least 50 km/h before the vacum valves openeds the bypass in the mufflers.

Regards

If you add the PSE to your Boxster and do not have it integrated, do they need to do any ECU reprogram for it? Or is that only if it is fully integrated?

Randall, you do not need to intergrate into the DME (correct term, not an ECU for Porsche). It will be in Sport mode at all times.

That is what I thought, and I will skip the DME integration and keep it in sport mode at all times (and skip the trip to the dealer)

Thanks!

Good call. You will need to "cap off" the vacuum lines that are part of the PSE, so dirt is not sucked into the exhaust. My dealership just just some type of rubber caps. The advantage of having it in Sport mode at all times is that it works when driving at lower speeds.

I thought the vacuum lines provided the suction to open the dampers ? For anyone interested Capistro offer a controller box for their exhaust. I beleive the exhaust is make by strosek in germany and like the porsche PSE has vacuum valves to open the bypass. I know of a guy in the Uk that had the full PSE fitted to his 2005 Boxster S , though it was already equipped with the sport chrono. The vacuum tapping points and plugs for the control module are not present in the pre 2007 model boxsters though I beleive a skilled porsche technician can wire back directly to the rear DME.

A vacuum from the engine opens the PSE valves. The PSE valves are normally open (loud).

Dirt in the vacuum lines would not affect the engine.

You mean vacuum closes the valves ? Surely this would mean the car starts with the PSE open and in loud mode ? Sounds a little backward in control terms but i will take your word for it.

The valves moved (to what I call closed) when a vacuum is applied - this routes the exhaust through additional baffles to make it quiet.

The default is (what I call open) - the valves do not have vacuum applied and the exhaust is loud.

I have stated this several times before - sorry if I somehow made it unclear this time.

A non leaking vacuum spare tank and hoses should hold him quiet for a day (or two), there is only a slight different sound noticeable for a split second on start up.

I just got my PSE installed today and it sounds great! Plugged the vacuum lines so no dirt in there, but hey, I will never fully wire it in. Well worth what I paid for the exhaust and installation.

Not connected vacuum line=Loud(ish)!

Having read the fitting instructions and now purchased a set of used mufflers I can see how the system works. As Loren stated previously , the vacuum from the inlet manifold pulls the sprung loaded valves closed , thats why the exhaust is in loud mode when you initially start up. I'm still undecided if I will install exactly as per OEM or leave an option to control the valves manually by a switch. Either way , i'm looking forward to fitting this system as an enhancement.
