Heard a lot about “Pedro’s sport exhaust” mod. Seen a few pics of others mods but searched like crazy & can’t find pedros original thread. Also, from what I’ve seen, got a few questions

Adding bypass pipes is nothing new. First saw it 3 1/2 years ago on German ebay. Made by a guy named Andreas Herrmann near Stuttgart. I contacted him back then. He also used vacuum valves on the pipes and opens the muffler to modify the inside. Follow all the links as I asked about it on a German Boxster board. http://www.renntech.org/forums/index.php?s...entry4479 Andreas was clever. Porsche had not yet come out with a sport exhaust that would fit a 2003-2004.

Then about 2 years ago I saw a similar version on German ebay and a UK Boxster board that only has they bypass pipes. No valves and the muffler is not opened. This is made by Marcus at Oettle, also near Stuttgart. http://www.renntech.org/forums/index.php?s...5&hl=bypass This is the Oettle site. http://oettle-autodienst.de/pageID_4231071.html

Then this guy from Spain came up with his own version that involved the uses of mechanical valves on the bypass pipes. http://www.renntech.org/forums/index.php?s...9&hl=valves

3 1/2 years ago there was yet another German ebay seller who was also modifying mufflers. When I was in contact with Andreas he said this guy use to work for him. I always wondered if this was Marcus.

I have the Oettle muffler on my '02 S and love it. It is very discrete, but has a nice deep tone and opens up as you get on the throttle. No drone or resonance due to the fact that it is a factory muffler, only modified.
