The SOUL X-Pipe Exhaust is the answer. We had modularity in mind – you can switch tips out or add our catted or catless pipes at any time. Support for high power was another consideration – necessitating 3″ tubing. We experimented with adding a mixing chamber into our X-pipe design. Analysis in 3D CAD software showed a general increase in velocity gained downstream of the mixing chamber across a band of measured pressure and temperature levels. This produces optimal flow characteristics, reduced backpressure for higher HP, and enhances the sound quality of the system.

Most 991 cars with 30,000+ miles should have this cleaned, as even a tiny amount of build-up can effect the idle speed.

The system removes the factory muffler, but still enables the original Sport Exhaust valve switch to work by closing half of the exhaust system when the system is disabled. In the open mode, it's noticeably louder than the original PSE system and gives drivers more joyful turbo whistling sounds. Our exhaust sounds deeper and more exotic than the factory system, but still does not drone or have resonance at freeway speeds. You can still close the valve when you need to make a call or prefer the sound of your stereo.\u003c\/p\u003e\u003cp\u003eWhen using Sport and more aggressive modes, you'll have more popping and burbles on overrun than before, but you can still tame this by using the Standard drive modes.\u003c\/p\u003e\u003cp\u003eOur exhaust is made from CNC mandrel bent stainless steel in the USA, assembled by hand and built-to-order. It will only fit cars with the factory Sport Exhaust System and its center-exit tips. It re-uses the original exhaust tips and is compatible with the switching valve system. This exhaust was independently dynoed and results showed 21 HP to the wheels across all RPMs and about 18 lb-ft torque gains. The exhaust also removes about 12 pounds from the rear of the car.\u003c\/p\u003e\u003cp\u003ehe exhaust is emissions friendly in that it does not alter or remove the catalytic converter or header system on the car, and it will not trigger check engine lights.

This exhaust will not fit the S or GTS models.\u003c\/p\u003e\u003cp\u003eThe 2017+ 991.2 Carrera was an incredible step forward in terms of horsepower and torque, as well as chassis and suspension improvements. But as we heard from the exhaust when we first tested the car and from repeat customer feedback, it's just not sporty or loud enough for many people who are used to the rumble of a flat six. If your car was optioned with the factory Porsche Sport Exhaust (PSE), you may be content with the sound of the original system, but for those who lack this option, they may want something a bit more representative of the car. Our exhaust was designed to give the new Carrera a sports car sound for a fraction of the price of the factory PSE upgrade retrofit.\u003c\/p\u003e\u003cp\u003eThis exhaust system was designed with maximum performance in mind so we used free-flowing mandrel bent tubing: there is no X-intersection or crossover, as these will restrict exhaust flow albeit slightly. The system removes the factory muffler, which gives drivers more turbo whistling sounds, removes about 10 pounds from the original system, and though we have not had a chance to dyno this system yet, we do expect it to add approximately 15 RWHP to the 3.0 Turbo motor found in the 991.2 Carrera (our similar PSE system dynoed at over 20 HP to the wheels increase on PSE equipped GTS models). Our exhaust sounds deeper and more exotic than the factory system, but still does not drone or have resonance at freeway speeds.\u003c\/p\u003e\u003cp\u003eOur exhaust is made from USA stainless steel and built-to-order by hand in California. It will only fit 991.2 Carrera models without the factory PSE-upgrade. The exhaust re-uses the original exhaust tips so the look from outside the car is OEM.\u003c\/p\u003e\u003cp\u003eThe ehaust is emissions friendly in that it does not alter or remove the catalytic converter or header system on the car, and it will not trigger check engine lights. Installation time is typically about 1.5 to 2 hours and is completely reversible, with no cutting or welding required . All required gaskets and hardware for installation are included with the product. We designed the exhaust for an exact fitment with the other original components so it should not be difficult or frustrating to install for qualified technicians.\u003c\/p\u003e\u003cp\u003eThis exhaust is significantly louder than the original, particularly when cold-starting the vehicle, revving at a stop, and under wide open throttle. That said, due to the nature of the car's original catalytic converters and turbochargers, the car is still tame under most normal conditions and can be driven in traffic and city environments without too much added attention. It's difficult to describe how loud an exhaust is from videos and descriptions online, but we do believe this video is representative of the product's sound.

For a $150,000+ car, it could certainly use more of an exotic growl along with more of a turbo spool\/whine that is customary with turbo cars of yesteryear.
