Porsche GT4 / Boxster Spyder Valved Exhaust System


The GT4 is a masterfully built machine from Porsche. The 3.8L emits a distinct wail that is so incredible that it is begging to be amplified. Our Valved Exhaust System is designed to help you extract the most potential from your GT4 while still being streetable.

While in quiet mode with the valves closed you will have a refined and sporty sound with no drone (with stock headers) at highway speeds and retain the ability to quietly enter and exit your neighborhood without annoying those around you thanks to the high quality mufflers. We know that a lot of owners plan on running catless headers on the street and minimizing drone was a goal of ours. Unlock the valves and you’ll be ready to turn off the radio, roll down the windows and hit your favorite back roads or go hard at the track. Every blip downshift will emit an incredible bark that will make the hairs on the back of your neck stand up.

Each system is made from mandrel bent T304L stainless steel tubing and features mufflers with fortified casings in the interest of durability. You can order this exhaust to suite your specific aesthetic desires – select from our Signature Satin or a full polish finishes, with tips of your choosing. You can drive in confidence knowing that you have the best sounding, best performing exhaust backed by the industry leading Soul Performance Products Lifetime Warranty.
