Titanium Ceramic-Coated Resonated OPF Delete Pipes with Resonator for Porsche 718 Cayman GT4 RS – Maximum Sound, Performance & Weight Reduction
These titanium ceramic-coated resonated OPF delete pipes
are engineered specifically for the Porsche 718 Cayman GT4 RS,
delivering a significant performance and acoustic upgrade over the standard-fit
exhaust configuration. Designed to replace the restrictive petrol particulate
filter (OPF/GPF) sections, this system dramatically improves exhaust flow while
maintaining refined sound control through resonated construction.
Fits:
- Porsche Cayman GT4 RS 718 4.0L
Manufactured from high-grade titanium and finished
with a ceramic heat-resistant coating, these pipes offer exceptional
strength, extreme weight reduction and reduced radiant heat
transfer—particularly beneficial around the rear tyres during aggressive road
or track use.
What is a Resonator
An exhaust resonator refines exhaust sound by cancelling unwanted frequencies such as drone and rasp. Positioned between the catalytic converter and muffler, it shapes tone rather than reducing volume, creating a smoother, more controlled exhaust note
What These OPF Delete Pipes Do
This performance exhaust upgrade:
- Removes
restrictive OPF/GPF sections from the exhaust system
- Improves
exhaust gas flow, allowing the engine to breathe freely
- Delivers a more exotic, motorsport-inspired exhaust note
- Enhances throttle response and acceleration
- Reduces exhaust system weight dramatically
- Lowers radiant heat build-up in the rear wheel area
Designed for drivers seeking maximum engagement, performance and sound from their Spyder RS.
Why Standard OPF Exhaust Sections Restrict Performance
Standard-fit OPF exhaust components are designed primarily for emissions compliance and often cause:
Excessive exhaust back pressure Reduced power and throttle response Muted exhaust sound High exhaust system weight Increased heat retention near the rear axleOn high-revving RS models, these restrictions significantly limit the engine’s true potential.
Why These Titanium OPF Delete Pipes Should Be Fitted
Replacing the original OPF sections with this titanium
system provides:
- Minimum
gains of 30hp+ through improved exhaust flow
- Massive weight reduction Standard OPF pipe set: 13kg 9m titanium ceramic-coated pipes: 3.8kg Total saving: 9.2kg
- Sharper throttle response and faster acceleration
- Reduced
thermal load around suspension and tyres
- Long-term
durability thanks to titanium construction
- A refined yet aggressive exhaust tone due to resonated design
This upgrade transforms the driving character of the 718 Boxster Spyder RS.
Important Technical
Note
European-spec
vehicles require a compatible ECU calibration (such as the 9m ECU
remap) to prevent an engine warning light after OPF removal.
