Fabspeed Exhaust
The Fabspeed Porsche 981 Boxster/Cayman Maxflo TRUE X-Pipe with Dual Tips is a performance exhaust upgrade designed for 2013–2016 Porsche 981 Boxster and Cayman models equipped with factory OEM mufflers.
Fits:
- Porsche Boxster 981 2.7L 2013-16
- Porsche Boxster 981 S / GTS 3.4L 2013-16
- Porsche Cayman 2.7L 981 2013-16
- Porsche Cayman S / GTS 3.4L 981 2013-16
Designed to replace the restrictive factory outlet/tip arrangement, the Fabspeed TRUE X-Pipe provides a smoother crossover path for exhaust gases while adding larger, more aggressive dual exhaust tips. The result is an upgrade intended to improve exhaust flow, enhance sports-car sound and give the rear of the vehicle a more purposeful appearance.
Constructed primarily from T304L stainless steel, the system is supplied with new installation hardware and 4-inch / 102 mm dual exhaust tips.
What This Product Does:
The Fabspeed Maxflo TRUE X-Pipe changes the way exhaust gases from the two sides of the exhaust system converge before exiting through the tailpipes.
The factory outlet arrangement directs exhaust gases toward a common outlet using a more restrictive crossover configuration. The TRUE X-Pipe introduces a smoother crossover path designed to allow the exhaust streams to merge and exit more efficiently.
This design is intended to:
- Improve exhaust-gas flow
- Reduce restriction at the rear exhaust outlet
- Provide smoother exhaust pulse interaction
- Increase exhaust velocity
- Enhance exhaust sound
- Support improved engine response
- Complement other performance exhaust modifications
- Provide a more sporting exhaust character
Unlike a complete muffler replacement, this product works with the factory Porsche mufflers, making it a relatively straightforward exhaust upgrade.
Performance Benefits:
Fabspeed designed the TRUE X-Pipe to improve exhaust flow compared with the factory outlet configuration.
By creating a smoother path for the exhaust gases, the system is intended to reduce unnecessary turbulence and restriction as gases leave the factory mufflers.
Potential benefits include:
- Improved exhaust flow
- Reduced outlet restriction
- Sharper throttle response
- Improved horsepower potential
- Improved torque potential
- More pronounced sports-car exhaust sound
Fabspeed describes the performance improvements as dyno verified. Actual horsepower and torque changes can vary depending on engine condition, vehicle specification, fuel, ambient conditions and other modifications.
Why Upgrading Matters:
The Fabspeed TRUE X-Pipe is primarily a performance and sound upgrade, rather than a routine replacement component.
Owners may choose the system to achieve:
- Improved exhaust flow
- A more sporting exhaust note
- Improved performance potential
- More distinctive rear styling
- Larger dual exhaust tips
- A straightforward bolt-on modification
- Compatibility with the factory Porsche mufflers
This makes it particularly suitable for owners who want to enhance their Porsche 981 without immediately replacing the complete rear exhaust system.

The Fabspeed Porsche 987 Boxster / Cayman Maxflo True X-Pipe with Dual Tips is a direct bolt-on exhaust outlet upgrade designed to improve exhaust flow, sound and rear-end appearance.
Fits:
- Porsche Boxster 987 2.7L 2005-08/08
- Porsche Cayman 2.7L 987C 2006-08
Unlike a complete rear muffler system, this component replaces the factory Porsche T-style exhaust outlet and tips while retaining the existing mufflers. Fabspeed's True X-Pipe design allows exhaust gases from both sides of the system to merge and transition more smoothly before exiting through the dual 4-inch / 102 mm tips.
The result is a freer-flowing exhaust outlet with a sportier flat-six sound and a more purposeful rear appearance.
Fabspeed lists manufacturer-reported gains of +8 HP and +5 lb-ft, together with approximately 3 lb of weight reduction. Actual results will vary according to vehicle specification, condition and testing environment.
What This Product Does:
The standard Porsche exhaust outlet directs gases from the two rear mufflers into a common centre outlet.
Fabspeed's Maxflo system replaces this arrangement with a true X-pipe design.
The crossover is designed to provide a smoother transition as exhaust gases from both sides meet and leave the rear mufflers.
The upgrade is designed to provide:
- Improved exhaust-gas flow
- Increased exhaust velocity
- Reduced turbulence at the exhaust outlet
- Improved performance potential
- Increased exhaust volume
- Smoother flat-six exhaust tone
- Sportier rear appearance
- Larger 4-inch / 102 mm dual exhaust tips
True X-Pipe Design:
The key feature of this product is the True X-Pipe crossover.
An X-pipe allows the exhaust streams from both sides of the engine to merge progressively rather than meeting through a restrictive T-style junction.
A smoother crossover can help:
- Reduce exhaust turbulence
- Improve gas velocity
- Improve exhaust pulse interaction
- Reduce unnecessary flow restriction
- Produce a smoother exhaust note
Fabspeed states that its X-pipe provides improved flow compared with the factory Porsche outlet design.
Direct Replacement For The Factory Outlet:
- The Fabspeed Maxflo X-Pipe is designed as a direct replacement for the original Porsche T-outlet style tip assembly.
- This means the factory mufflers remain in position.
- The product is therefore an attractive option for owners who want improved flow, appearance and sound without replacing the complete rear exhaust system.
Why Upgrading Matters:
The factory exhaust outlet does not need to have failed before fitting this product.
The Fabspeed Maxflo True X-Pipe is primarily a performance, sound and styling upgrade.
Reasons for upgrading include:
- True X-pipe crossover design
- Improved exhaust flow
- Increased exhaust velocity
- Reduced outlet turbulence
- Manufacturer-reported +8 HP
- Manufacturer-reported +5 lb-ft
- Approx. 3 lb weight reduction
- Sportier flat-six exhaust sound
- Mild increase in exhaust volume
- Large 4-inch / 102 mm dual tips
- Multiple tip finishes
- T304L stainless-steel construction
- Carbon-fibre option
- Direct replacement for the factory outlet
- Retains the original rear mufflers
- Simple bolt-on installation
- No cutting or welding required
