Sounds like an expensive button for something you will probably want open all of the time.

Haha, I installed a similar button on my 2004 VW a few years ago. Cost about $6 in parts.

My buddy did the same thing on his R32.

Yet another thing to go wrong...

I have thought about this idea for my 993. There was a thread way back about using an electric valve (you can get them on the net...actually you can get practically anything on the net!) to bypass the mufflers on command. It would require a Y in the exhaust stream. I thought it was a neat idea, but I was not sure about the longevity of the valves, etc. But then life interrupted me, and I got too busy to think about it again...

Is this different than the PSE that was originally offered on the 997's when they first came out?

I had PSE on the '05 997 that I owned but it was always set on the "Sport" setting and made a fabulous sound.

A lot of cars have this now, it's just a vacuum operated solenoid, like the Varioraom ones.
Most open above 5000rpm, or full throttle. Most people, remove the vacuum line, & cap the exhaust open.

If you see a new Corvette, you can see the 2 big solenoids & flaps on the center 2 outlets. BMW, Audi, & Ferrari all have this.

Sounds like a good DIY on pcarworkshop.com

It must be different I guess.

I took off my mufflers, and my push-button exhaust sound comes when I push the lever to lower my window.

So we arrive into the age of a "muffler bearing".

who buys a sports car to be quiet? Of course the site mentions this will be available for older models as well.

ploglet

this sounds very similar to the Kreissieg F1 exhaust system. Both too expensive.

RUF also makes exhausts likr this, right? Even for the 993.

I had started a couple of threads about this and actually bought the valves...

The electric valves are too big to fit in the area between the inlet and exhaust.

Turns out, I went with the LPMM and it is pretty darn good with no messing around with valves.

I am glad I didn't try to have a valve that just opened up a bypass. The LPMM allows some gas to go throught the muffler as it does not completely close off the muffler. The LPMM just allows gas to bypass.

So to me now that I have had the LPMM, I would have been very dissapointed with the "valve allowing the bypass" type of design.

Now if I wanted a valve, I would put it between the LPMM bypass and the inlet to the muffler so the muffler would perform like the LPMM when the valve is open . That way from the drivers seat, you could CLOSE the muffler and force all of the exaust out the bypass.

I might need pictures for this so lemme look!

Cheers!
