Think I'll email back and ask them to clarify.

Also glad to hear you like the PSE. From everything I've read while researching it people seem to love the PSE systems.

Wild, you might be able to do the work yourself. When you call Sunset, ask them for the Technical Bulletin. This will give step-by-step install instructions, and is the same document the dealership uses. In there it will also list the labor time units. You can use this to negotiate a more fair price with the dealership and keep them honest. Most dealerships charge about 2x's the time units.

For the price they quoted I'm already thinking that way. I emailed them back and gave them the tequipment part number just to confirm we're talking the same thing. I'm wondering if he included price of new cats by mistake.

I also emailed a local independent Porsche shop I've heard good things about. I know the some of pro athletes in the area go there.

My '08 Boxster S should be here in a couple weeks and it will have the PSE - I understand that it does not really kick in so to say until the RPMs are up...I've heard that to have it "on" all the time I would have to disconnect the vacuum lines - is that what is meant by "bypassing"? If so, is it an easy job?

Thanks in advance...Bob Z.

Yes, just take off the vacuum lines. and then protect the lines and any exposed openings.

That's the easy and quick way.

You can also, after gaining access to the engine, splice a switch into the wires that control the vacuum unit, locate the switch inside the cabin (I placed mine in the ashtray) and control it yourself. What this does is interrupt the signal from the DME which tells the vacuum unit to either open or close the valves.

It's not that hard and allows you to either run it the way the factory made it or stay in loud mode until you switch it back.

Hope this helps.

All the best,

PS: This is for a 2007+ style PSE.

For normal driving, say keeping RPM's below 4,000, there isn't much of a sound difference between "loud" mode and "quiet" mode. That is the beauty of this exhaust system and what keeps resonance so low. At 6,000 RPM, now thats a different story.

I disagree. There is quite a lot of difference. But it's a pleasant difference -- not obnoxious at all.

Steve is right in that it really starts sounding great at the higher revs. 4,200 it starts getting good. 5,000 on up start thinking Carrera GT -- not Boxster.

To me, however, it does sound a little congested at WOT and above, say, 6,500 rpm. As if it's blowing through some more cats and baffles than it ought to (which it is).

Have you seen the new Borla system? Not much restriction there! I don't know about sound and you can't switch it into quiet mode, but...

All the best,

PS: If Steve has the factory system as installed by the factory, it will close the valves from about 10 to about 45 or 50 mph for Euro noise requirements and that may be why he said it was not much different. Unplug the vacuum lines for the easy way to hear it always in loud mode (do plug the ends and secure them up out of the way, though).
