DOES MY CAR HAVE “PSE”?

The Porsche Sport Exhaust – better known as PSE – was a factory option available on many late model Porsches. You can quickly and easily determine if your vehicle is equipped with PSE by taking a look at your center console. If your console has a button on it with an “exhaust tip” icon (see photo), then your vehicle is equipped with PSE.

  1. Quality Product, Excellent Fitment, Noticeable Power Gains! 5 Star Review

    Posted by on 31st Jul 2017

    I had the bypass pipes recently installed on my 991.2 S. The fitment was exact, no adjustments required for direct bolt on application. I also installed the 45 catted o2 spacers, which fit perfectly and prevented a CEL.

    The bypass pipes provide immediate spool up which even in a stock tune provides a more linear power delivery. There is noticeable power throughout the rpm range as well as up top. With the valves closed the car sounds stock, open the volume has increased but it is by no means intrusive.. on par with an aftermarket exhaust. The exhaust tone is more bass-y and aggressive.

    I highly recommend this product, worth the build time!
