The SOUL Race Exhaust System is designed for Porsche 981 Cayman GT4 and Boxster Spyder owners who prioritize maximum sound, reduced weight, durability, and track-focused performance. Developed specifically for aggressive track use, the system replaces the factory rear exhaust with a purpose-built architecture engineered to withstand sustained high-temperature, high-RPM operation while delivering an extremely aggressive naturally aspirated flat-six exhaust note.
Full 2.5-inch over-axle piping provides a free-flowing exhaust path while maintaining clearance around the axles and sway-bar end links, including on heavily modified or lowered vehicles. Rather than relying on conventional exhaust hangers welded directly to the piping, SOUL developed a dedicated transmission-mounted support system designed to improve durability under demanding track conditions.
The forward exhaust piping attaches to a bespoke SOUL transmission mounting brace using heavy-duty Mikalor band clamps. Additional rubber vibration dampeners support the over-axle piping and help isolate movement and vibration throughout the exhaust assembly. SOUL's mounting solution alone removes more than 5 lbs compared with the factory mounting hardware.
The complete system is constructed from mandrel-bent .065-inch-wall, 2.5-inch-diameter T304L stainless steel tubing. Laser-cut and press-brake-formed brackets are TIG welded for strength, while all exhaust welds are back-purged to improve durability and longevity under extreme operating conditions.
This is an intentionally aggressive exhaust system. SOUL designed it primarily around track performance rather than sound attenuation and specifically describes it as very loud. Cabin drone will still be present despite the resonated design, particularly during sustained cruising. For owners looking for the rawest and most track-focused exhaust configuration for the 981 GT4 or Spyder, the Race Exhaust delivers maximum exhaust presence without the complexity of a valved system.

Alternate tip finishes are available by special request
Backed by SOUL Performance Products' Lifetime Warranty for both street and track use
Designed and manufactured in-house at SOUL Performance Products in Willow Grove, Pennsylvania
The SOUL Race Exhaust System was developed primarily for track use and performance rather than maximum sound attenuation.
SOUL describes the system as very loud and specifically notes that cabin drone will remain present even with the resonators. Pairing the Race Exhaust with aftermarket headers will further increase overall exhaust volume and intensity.
SOUL does not recommend using the Race Exhaust together with aftermarket headers for normal street driving. Owners looking for a more refined exhaust experience with the ability to reduce volume when desired should consider the SOUL Valved Exhaust System instead.
The SOUL Race Exhaust is designed to fit vehicles equipped with the factory Porsche headers or compatible SOUL headers.
Because over-axle pipe clearance is intentionally optimized for the GT4 / Spyder chassis, dimensional differences in some third-party aftermarket header systems may create clearance issues. Customers using non-SOUL aftermarket headers should confirm compatibility before ordering.
This DasMotoring listing includes SOUL Slash-Cut exhaust tips in Signature Satin.
To keep ordering simple, alternate tip finishes are not offered through the standard product options. If you would like a different SOUL tip configuration, contact DasMotoring before ordering and we can confirm availability and pricing.
This Race Exhaust is specifically listed by SOUL for the 2015–2016 Porsche 981 Cayman GT4 and Boxster Spyder.
The 981 GT4 Clubsport is not included in SOUL's published fitment for this particular Race Exhaust System and should not be assumed compatible.
This product is not CARB certified and may not be legal for use on emissions-controlled vehicles. SOUL identifies the system as intended for off-road use only.
