- Porsche Cayman GT4 3.8L 2015-16
The Fabspeed Deluxe Bolt-On Tips are a performance and styling upgrade designed primarily for the 2015–2016 Porsche 981 Cayman GT4 and 981 Boxster Spyder equipped with factory mufflers.
Fits:
- Porsche Cayman GT4 3.8L 2015-16
Unlike a purely cosmetic exhaust-tip replacement, the Fabspeed design incorporates a true X-pipe outlet arrangement intended to improve exhaust flow while giving the rear of the vehicle a more distinctive performance appearance.
The system features dual 3.5-inch outlets manufactured from high-quality T304L stainless steel, with selected versions incorporating genuine carbon-fibre outer sections.
The assembly directly replaces the factory exhaust outlet / H-pipe tip arrangement and installs without cutting or welding.
What This Product Does:
The factory exhaust outlet assembly connects the two sides of the rear exhaust system before directing gases through the central exhaust tips.
Fabspeed replaces the standard outlet arrangement with a true X-pipe crossover design.
The X-pipe allows exhaust gases from the two cylinder banks to merge more smoothly, helping reduce turbulence and improve exhaust flow.
Its main functions and benefits include:
- Improving exhaust gas crossover and flow
- Replacing the factory outlet / H-pipe assembly
- Producing a sportier exhaust character
- Increasing the visual presence of the rear exhaust outlets
- Providing dual 3.5-inch exhaust outlets
- Supporting improved engine response
- Providing a direct bolt-on performance upgrade
Fabspeed states that its CAD-designed and dyno-developed X-pipe can produce up to approximately 12 horsepower more than the factory Porsche H-pipe outlet arrangement in its testing. Actual gains depend on vehicle specification, condition and operating conditions.
Symptoms Of Wear Or Failure:
The factory exhaust outlet and tip assembly is exposed to high exhaust temperatures, moisture, road debris and repeated thermal cycling.
Signs that the original assembly may require replacement include:
- Heavy corrosion
- Pitting or rust around the exhaust outlets
- Permanent staining or discoloration
- Scratched or damaged exhaust tips
- Dented outlets
- Cracks around welds
- Loose mounting hardware
- Exhaust rattles
- Movement in the outlet assembly
- Poor exhaust-tip alignment
- Exhaust tips contacting the bumper or diffuser
- Black soot around leaking joints
- Blowing or hissing from connections
- Damaged or distorted crossover pipework
- Excessive exhaust leakage
Cosmetic discoloration alone does not necessarily indicate failure, particularly on a high-performance vehicle where exhaust temperatures can be considerable.
Why Replacement Matters:
Where the original exhaust tips are simply faded or scratched, replacement is primarily a cosmetic decision.
However, physical damage to the outlet or crossover assembly can create more significant issues.
A loose, cracked or poorly aligned exhaust outlet can cause:
- Rattling during driving
- Exhaust leakage
- Hot gases escaping near surrounding components
- Contact with the rear diffuser or bumper
- Heat damage to nearby trim
- Poor exhaust alignment
- Continued deterioration of mounting points
Replacing a damaged assembly restores secure mounting, correct exhaust routing and proper clearance around the rear bumper.
For vehicles with a healthy standard outlet assembly, the Fabspeed system is primarily a performance, sound and appearance upgrade.
