Product Specifications

Frequently Asked Questions

What are OPF and GPF delete pipes?

OPF means Otto Particulate Filter, while GPF means Gasoline Particulate Filter. Both terms describe factory particulate-filter assemblies located in the exhaust system.

FMF Elite Over-Axle Pipes replace these assemblies on compatible Porsche 718 Cayman GT4, 718 Spyder and Cayman GTS 4.0 vehicles.

Will these OPF delete pipes trigger a check-engine light?

FMF designed these pipes around the North American exhaust, sensor and diagnostic configuration to reduce the risk of check-engine lights and fault codes commonly associated with incompatible OPF delete pipes.

Operation can be affected by vehicle software, sensor condition, existing modifications and installation quality. Compatibility cannot be guaranteed across every software version or modified vehicle.

What does an over-axle pipe do?

The over-axle pipes connect upstream exhaust components to the rear exhaust while passing through the rear axle area. Replacing them changes this section of the exhaust path without replacing the headers or complete rear exhaust system.

Is an over-axle pipe the same as a complete exhaust?

No. These pipes replace only the factory over-axle pipe assemblies. They do not replace the complete exhaust, headers, catalytic converters or rear muffler.

Will these pipes fit every Porsche 718 GTS?

No. These pipes are designed for compatible Porsche 718 Cayman GTS 4.0 models. They are not intended for earlier four-cylinder 718 GTS applications.

Will these pipes fit the Porsche 718 Cayman GT4 RS or Spyder RS?

No compatibility with the Porsche 718 Cayman GT4 RS or Spyder RS is claimed under this product listing. Those vehicles require application-specific components.

Will these pipes fit a European-specification vehicle?

These pipes are designed for compatible North American vehicles. European models may use additional ports or a different sensor configuration and should not be assumed compatible.

Should I choose stainless steel or titanium?

Choose 304 stainless steel for excellent durability, corrosion resistance and value. Choose titanium if reduced weight and premium motorsport construction are your priorities.

What does the Cerakote coating do?

The optional Cerakote coating adds a durable ceramic-based finish and helps control radiant heat around nearby components. It also provides a distinctive custom appearance.

Is professional installation recommended?

Yes. Professional installation is recommended to ensure correct alignment, suitable component clearance and leak-free exhaust connections.
