SOUND: If you're looking for a really aggressive exhaust note and you're not worried about waking up the neighbors, this is the system for you! This exhaust will deliver ripping sports car sound, at the cost of some interior drone. The Supercup is significantly louder than our Maxflo Exhaust, but If you want the best of both worlds, check out our TrackTec Valved Exhaust, which will be slightly louder than the Supercup with the valves open and just as civilized as our Maxflo system with the valves closed.
POWER: By dyno designing this system specifically for the Porsche 981 Boxster/Cayman platform, we've been able to squeeze the most horsepower possible. Our dyno testing showed an increase of 15 whp and 19 ft-lbs of tq at 4000 RPM. Peak gains are 11 whp and 11 ft-lbs of tq.
FEATURES:
• Fits all Porsche 981 Boxster/Cayman vehicles (2013-2016)
• Includes deluxe dual style tips in your choice of satin black, carbon fiber, or Polished Stainless Steel
• Improves power by 15 whp and 19 ft-lbs of tq
• Complies with all U.S. emissions regulations
• Saves 15 lbs from the rear of the vehicle compared to the full OEM exhaust system
• Straight through design uses two 2.25" resonators to minimize weight and improve top-end performance
• Constructed from high quality 14-16ga CNC mandrel-bent T304 stainless steel for maximum performance and durability
• Noticeable improvement in sports car sound and throttle response
• Bolt-on with no cutting or welding required
• All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty

Experience the perfect balance of refinement and excitement with the SOUL Street Package for Porsche 981 Boxster and Cayman models. This system pairs SOUL Valved Exhaust with Long Tube Street Headers, delivering noticeable power gains, sharper throttle response, and a soundtrack that adapts to your driving mood—all without triggering a check engine light. With valves closed, the system offers a smooth, drone-free tone ideal for daily driving. Open the valves, and the flat-six unleashes its full roar through a straight-through flow path, exiting via exhaust tips in the style and finish of your choice. Built around large-diameter runners and high-flow catalytic converters, the headers maximize flow while enhancing that signature Porsche sound. Every system is backed by our industry-leading Lifetime Warranty, giving you confidence both on the street and at the track.
Package Includes:
• SOUL Performance Products 981 Cayman Valved Exhaust System
• SOUL Performance Products 981 Cayman Long Tube Street Headers
• Fits all Porsche 981 Boxster / Cayman models (2013–2016)
• Increased performance and sound with no check engine light
• Direct bolt-on installation with included instructions
• Multiple tip styles and finishes available – custom options too
• Covered by SOUL’s Lifetime Warranty for street and track use
DEVELOPMENT:
For the 981 platform, we engineered a system with properly sized 2” runners and optimized collectors to unlock maximum power from the 3.4L engine, while still delivering impressive gains on the 2.7L. We selected high-flow catalytic converters sized for both performance and durability—avoiding the compromises of smaller, cheaper alternatives. The result is a superior exhaust that delivers a broad spectrum of sound: valves open reveal a CUP car–inspired roar, while valves closed provide a refined, drone-free tone. Thanks to SOUL mufflers, even with aftermarket headers the exhaust remains composed and reserved when the valves are shut.
CONSTRUCTION:
Our headers are precision-engineered and crafted from T304L stainless steel for strength and performance. Featuring port-matched flanges, smooth-radius primary tubing, and optimized collectors, they deliver maximum exhaust flow and power gains. Each system is mandrel-bent, fitted with reinforced muffler casings for durability, and rigorously quality-checked before shipping to ensure the highest standards.
TIPS:
Choose from several different tip styles and finishes – from single wall 321 stainless tips to double wall chrome tips. Logo customization and custom tip colours are available by request. Titanium single wall tips are also available and save nearly a pound of weight over stainless steel tips!
BOLT ON AND GO:
Each exhaust is rigorously quality-checked, tested in a fixture to guarantee fitment, and then foam packed to ensure it arrives in perfect condition. Thorough installation instructions are included in the box for a straightforward install that can be performed by most DIY enthusiasts.
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.
