That's if you want the button and all the connections, right? The valves are normally open so you could install the muffler and leave it in the open condition full time.

The thread below explains it. On early Boxsters with the PSE option from the factory, there was no interior switch to control the valves. The exhaust was wired such that when the car went faster, the valves would automatically open. The early PSE had exterior shiny "sebring" style pipes that you could easily see from the rear. If you didn't get this option from the factory, many would just use metal cable wire to keep the valves open all the time, and this is fine as I'm not sure why anyone would want to silence the muffler, as even in the loud position, it wasn't all that loud. The 03+ PSEs sound better than the previous ones, as it had more growl.

On later PSEs from the factory (03 onwards), they got rid of the shiny exterior pipes, and so it looked like a standard exhaust from the outside except that the underside had valves and small pipes that couldn't be seen from behind the car. On these, there was a button on the upper console (shown in the thread below) that could open and close the valves at will. Honestly, the PSE is hard to come by now, and they don't drone, unlike most any other aftermarket exhaust (except the Dansk that I have as well as the home made PSEs done at muffler shops using the OEM muffler). If it were me, I'd keep the PSE and just get cat bypass pipes, but up to you to explore. You can definitely get a better sounding and crackling exhaust, but it will most likely come at the price of drone. Can you deal with that?

Factory PSE, where's the switch? - Rennlist Discussion Forums

The default for the PSE is for the valves to be open, louder. If you wire the valve plungers down you will be closing the valves making it quieter. I have verified this with a cable camera. If you add a PSE to you Boxster just leave it as it is for a louder note. Again, IMHO, the PSE look great but are lacking in sound.

I could've sworn I read a post before on Renntech where a guy wired his PSE valves so that they wouldn't close, but I defer to you since you have one.

Then I definitely need a new muffler. This thing is quieter than my FJ. I run around with a bunch of air cooled 911's and I cant even tell if my engine is running or not without looking at the tach!

Something is wrong with your valves (either stuck or getting constant vacuum).

Anyone seen a pipe bypass done on a base single tip exhaust? Where would you weld the pipes to make them look even half way decent?

Do a google image search for "Porsche 986 muffler bypass". Tons of pictures and yes, it looks fine.

This advice could've saved me concerns on a PSE months ago; I'll keep that in mind in my next opportunity for a PSE

Thanks!
