Product Information
Sports exhaust motorsport valvetronic kit. Kit includes rear and centre silencers.
FOR CARS WITHOUT GASOLINE PARTICULATE FILTER (GPF)

tubi

Fits:
Porsche 718 Boxster 2.0Ltr - No GPF
Porsche 718 Boxster S 2.5Ltr - No GPF
Porsche 718 Cayman 2.0Ltr - No GPF
Porsche 718 Cayman S 2.5Ltr - No GPF

The kit includes the central and the rear silencers
The kit can only be controlled via the remote control or the Tubi APP When this system is fitted on a car equipped with the optional Porsche sports exhaust system, the exhaust valve will not be controlled by the SPORT control
The component is perfectly interchangeable with the original components, following the instructions in the constructor's workshop manual.

RACETRACK USE ONLY
These components are designed and developed for racetrack use and to maximise the car's performance. They are not street legal and must be installed by professionals in the sector

ECU REMAPPING - FOR PERFORMANCE
On turbo cars, catalytic converter replacement may modify turbocharger operating conditions and cause a deterioration of the torque delivery curve. To ensure full benefit from the new racing component, the engine's ECU must be reprogrammed to maximise performance. If the engine warning light comes on, the ECU must always be reprogrammed to eliminate it

SOUND - + RUMORE
The + Rumore variant delivers the original Tubi Sound timbre but with the highest possible volume

VALVETRONIC SYSTEM - EXCU VALVETRONIC
The exhaust system is supplied complete of the Tubi Style Exhaust Control Unit. The control unit enables control of the standard Tubi Style exhaust system valve in 4 different modes tailored by Tubi Style, via APP and remote control. If this function is used, EC type-approval is no longer valid

END TIPS DIMENSION - 50mm
The value refers to the external dimensions of the exhaust end tip.

SYSTEM FINISH - POLISHED
Mirror finishes are highly reflective and created by polishing the stainless steel. The polishing process enhances appearance and consistency, making cleaning easier. A special rolling procedure is used. It is essential to remove deep scratches as any surface defects will be very noticeable on the finished product. it improves corrosion resistance. The polishing eradicates crevices where corrosive particles can lodge themselves

END TIPS NUMBER AND POSITION - 2 + 2 CENTRAL
There are two pairs of tailpipes with a gap between them, in the centre of the rear bumper

MATERIAL - AISI 304 STAINLESS STEEL
A choice stainless steel ideal for aggressive environments where combustion emissions can cause serious chemical corrosion on other types of metal

REDUCED CELL CATALYTIC CONVERTER - 100 CELLS
Race catalytic converters have fewer cells than standard factory systems. This reduces exhaust back pressure while still maintaining the operation of the catalytic converter, and improves performance and sound

EXHAUST VALVE - ELECTRIC
The exhaust system is complete with electric valve. The electric actuator is not included and the standard actuator already installed on the car must be used. Control of the original valve is still provided

HEAT SHIELDING - INSULATED
Tubi Style ensures maximum protection for components in critical and dangerous positions by using insulation made with the same technology employed by car manufacturers

Please note: sports catalytic converters or bypass pipes do have type approval and may not be legally installed on vehicles manufactured after 1st March 2001. They can not be used on a public road and are not MOT compliant, they are designed for race and track cars only.

About All Silencers / Mufflers

Standard Exhaust Systems – Engineered for Performance, Sound & Longevity

A standard exhaust system is essential for your Porsche’s performance, efficiency, and sound. It controls the flow of exhaust gases from the engine, reduces emissions, manages noise levels, and ensures balanced back pressure for optimal power delivery.

At Design911, we supply standard exhaust systems built from high-grade stainless steel and corrosion-resistant materials. Designed to meet or exceed manufacturer performance standards, these systems deliver the perfect blend of durability, refinement, and performance — ideal for both daily driving and restoration projects.

Each exhaust system is developed to ensure precise fitment, excellent gas flow, and an authentic Porsche exhaust note that retains the car’s original character.

What Do Standard Exhaust Systems Do?

A standard exhaust system performs several vital roles that keep your Porsche running efficiently, cleanly, and safely.

Core Functions:

  • Directs exhaust gases safely away from the engine.
  • Reduces emissions through catalytic converters and silencers.
  • Controls back pressure for balanced performance and fuel efficiency.
  • Minimises engine noise while preserving Porsche’s signature tone.
  • Aids temperature regulation and exhaust scavenging.

A properly maintained exhaust system ensures smooth performance, reduced fuel consumption, and compliance with emissions regulations.

Why Do Exhaust Systems Fail?

Exhaust systems are constantly exposed to heat, moisture, and corrosive gases — all of which take a toll over time.

Common Causes of Failure Include:

  • Corrosion and rust from road salt, condensation, and moisture.
  • Cracked welds or pipes due to vibration and thermal cycling.
  • Internal baffle damage causing rattling or loss of silencing effect.
  • Blocked or leaking joints leading to reduced performance and increased noise.
  • Burnt-out catalytic converters or mufflers reducing efficiency.

Signs of exhaust failure include loud noises, rattling, exhaust odours, or reduced engine performance — all clear indicators that replacement is required.

Why Replace Standard Exhaust Components?

Replacing a worn or damaged exhaust system restores performance, comfort, and efficiency while maintaining your Porsche’s distinctive exhaust tone.

Key Benefits:

  • Restores proper exhaust flow and back pressure.
  • Improves fuel efficiency and power output.
  • Reduces noise and vibration.
  • Ensures emissions compliance and MOT readiness.
  • Built from corrosion-resistant stainless steel for longevity.
  • Direct-fit compatibility for classic and modern Porsche models.

Upgrading to a high-quality standard exhaust preserves the car’s original performance characteristics while ensuring long-lasting reliability.

Highlights:

  • Precision-engineered exhaust systems for Porsche vehicles.
  • Optimised gas flow for power, torque, and efficiency.
  • Durable stainless-steel construction for corrosion resistance.
  • Designed for authentic tone and perfect fitment.
  • Suitable for classic restoration and modern maintenance.
  • Reliable, quiet, and performance-balanced solutions.
