Soul Performance

Soul Performance Products is proud to offer a valved exhaust for GT4 / Boxster Spyder owners who are looking for a refined increase in volume and aggression with an exhaust that's backed by a warranty for track use. There are plenty of race systems available, and we want to offer a more sophisticated option. We know that a lot of owners plan on running race headers on the street as well as the track and minimizing drone was a goal of ours.



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 our Lifetime Warranty! Our team will quickly work with you to resolve any issues or answer any questions that you may have.

Honest review from GT4 owner who approached us looking for a more refined option than the valvetronic exhaust system currently on his car:
"Nothing like a rush hour trip to check for exhaust drone. It’s just about perfect. Unlike the original, it even sounds like an internal combustion engine with valves closed. And above 4k it even sounds good with valves closed. But with valves open it sounds great. Not quite as loud as (competitors system), but also not as ragged and shriek-y. Better in all categories; sounds like a tuned engine. AND THE DRONE IS GONE. It’s not quiet (which I didn’t want). You know the engine is running (which I did). But you also know what your passenger is saying. This is really what I wanted in the first place. Thank you."

Thank you very much!

Bill just stopped in again today as we noticed some missing hardware on his headers during the exhaust install; we put in fresh Porsche hardware. Here's another quick video of some revs with valves closed and open.

Nice looking, thanks for posting, please tell us more!
How are the valves actuated - OEM switch or???

Soul Performance

Thank you! You can control the valves with the factory valve control
button. If you wanted you could wire up our valve controller to use the fobs - and you can pair our fobs with HomeLink as well.

We're looking forward to offering high quality PVD black coated tips in the near future as well!

Great video guys with high quality audio, & nice demonstration of civilized valves closed sound or serious sports car sound with valves open.
Looking forward to my Soul sport headers arriving soon & likely this exhaust in 2018.

Bruce, thank you for your support! They are on the way to Swain Tech Coatings, can't wait to see the end result!

We had the pleasure of getting to know Rennlist member DiabloBlanco and helping him outfit his Boxster Spyder with our Valved Exhaust. Tom was looking for a deeper sound out of his exhaust system and as he lives in CA, has CARB to consider. Fast forward to today and we're happy that he found exactly what we was looking for!

"I think the sound is awesome. Actually perfect. The goal was to create a deeper note but preserve the Porsche frequency (if that makes sense). I have only driven the car for 30 min or so but WHOA, what a difference. Even with the valves closed, it’s a little more aggressive than before. The installer said it sounds more like a GT3 now. He was pretty pumped up after installing it and was impressed."

What's the red piece between the two tow hooks in the first photo?

chillindrdude

that is a rear end jack point pad. allows one to lift both rear wheels off the ground.

Look very similar to the FVD system.

Sounds good

What a great idea, yet so simple.
Can't find it in your catalog, is it also for a different model?
