DEVELOPMENT: 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 factory headers and high flow catted 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.
CONSTRUCTION: Each system is made from mandrel bent T304L stainless steel tubing (featuring 2.5″ OD over axle pipes) and features mufflers with fortified casings in the interest of durability. With valves closed the exhaust gasses are routed into the SOUL muffler, which is packed with high quality sound deadening material designed to withstand abuse and not blow out over time. The mufflers are incredibly effective at minimizing drone. Exhaust gasses make their way through the muffler and out through perforations into the outer piping. With valves open, exhaust gasses are now free to exit out through large 2.5″ piping while perforations allow exhaust gasses to “talk” with the muffler, encouraging a fuller, more robust tone. Choose from single wall stainless tips (slash cut or straight cut) in our signature satin or brushed finish or chrome double wall tips.
BOLT ON AND GO: Each exhaust is rigorously quality-checked and tested in a fixture to ensure perfect fitment. Thorough installation instructions are included in the box for a straightforward install that can be performed by most DIY enthusiasts. Valves are controlled by the existing valve button, our valve controller fobs, and are compatible with HomeLink!
LIFETIME WARRANTY: Enjoy your SOUL exhaust components with confidence on both the street and track as they are covered by a Lifetime Warranty! Our team will quickly work with you to resolve any issues or answer any questions that you may have.
