The Porsche 718, project code Porsche 982, entered production in 09/2016, and introduces an important new central 4-cylinder Boxster engine, an innovation that aims to meet the requirement of reducing pollution emissions in the European market thanks to downsizing combined with introduction of turbo power.

First variant produced without GPF – from 2016 

The launch of the first variant of this model takes place with two engines that equip the Boxster and Cayman models produced until 08/2018 identically, and which are marketed all over the world with an exhaust line downstream of the turbo equipped with the catalytic converter only.

A 1,998 cc engine, which features in the standard versions, from 300 horsepower at 6,500 rpm, and a 2,497 cc engine, destined for the S version, from 350 horsepower at 6,500 rpm.

The public’s feedback is conflicting: if in terms of performance the car guarantees everything a Porsche must have, the feel with the engine is not always the best: the sound of the 4-cylinder boxster does not satisfy many customers.

The exhaust system is as follows, characterized by a single catalytic converter placed at the turbine outlet, which shortly after splits into a Y, inserting the silencer elements at the ends of these two individual branches.

The gases coming out of the two silencers then converge in a common exhaust tail, available in single or double pipe variants, with different finishes available.

Porsche offers the opportunity to improve the sound thanks to the classic optional PSE, the Porsche Sports Exhaust, which introduces a pneumatic valve on the right branch of the exhaust system, controlled by the control unit in a variable mode by pressing the sport button in the passenger compartment.

The valve intrdouced block the exhaust gas flow inside right exhaust line. This action creates a counter-pressure that creates a single flow that pass through the left side, with a not optimal fluid dynamic situtaion of the catback system.

This first generation remains unchanged in production until today in all markets where the GPF particulate filter has not been introduced, typically the whole world except Europe. For this first generation, Tubi Style offers different solutions:

200 CELLS RACE CATALYTIC CONVERTER for PORSCHE 718 2.0 and 2.5 TURBO w/o FAP

The racing catalyst replaces the original catalyst with a racing component with a smaller number of cells, and a consequent improved permeability that drastically reduces the exhaust back pressure.

This solution is perfectly interchangeable with the original components, and is specific for use on the track and not approved for road use. The solution allows you to increase and improve the sound of the car, but there are some key points to take into consideration:

• Replacing the catalyst changes the reading conditions of the OE lambda sesnor, which can lead to Check Engine Light ON, and the activation of the recovery system of the car, with rpm limitations.

• The decrease of the back pressure changes the operating conditions of the turbo: the original ECU maps of the car can be negatively affected, for example by introducing a significant torque gap in the mid-range.

The use of a sports catalyst creates the conditions for an increase in power, but its correct installation and full exploitation of its potential require a contestual ECU remapping performed by a professional.

MUFFLERS for PORSCHE 718 2.0 and 2.5 TURBO

Two kits of mufflers are proposed, specific for use on the track and not approved for road use, and perfectly interchangeable with the standard components.

• The muffler kit with pneumatic valve can be mounted on all Porsche 718s equipped with the optional PSE. The assembly of these mufflers allows maintaining the functionality of the Sport button and the control adjustments of the pneumatic valve, increasing the sound output, and customizing the tone.

• The valveless muffler kit can be fitted to both cars with standard exhaust and cars with optional PSE exhaust. In the case where the valve is removed, the control of the valve will be lost using the “sport” button in the passenger compartment, but all the other functions will remain unchanged. Porsche does not provide feedback controls for correct operation of the standard pneumatic valve, so removal will not cause the engine warning light to come on.

EXHAUST TAILPIPES for PORSCHE 718 2.0 and 2.5 TURBO

For an aesthetic customization, the specific TubiStyle tailpipes are in black colour and with a diameter increased to 94 mm.

All the components listed so far can be purchased individually to be coupled with the original components, or to form a single Tubi Style exhaust line, even at a later stage: starting with only the mufflers and tail pipes in the period covered by the guarantee, to then conclude the upgrade with the racing catalyst and the remapping at a later time.

For a more extreme use, we have created a complete single-pipe exhaust system, which carries the exhaust gases directly to the outlet along a single pipe. This solution minimizes the weight, and maximizes the efficiency of the system by avoiding the subsequent separation of the exhaust gases.

MOTORSPORT EXHAUST SYSTEM  for PORSCHE 718 2.0 and 2.5 TURBO w/o FAP

The exhaust line includes the catalytic converter, and a valve, in which the; silencing element is obtained through a reduced section valve by-pass duct.

It is offered in two variants:

• With pneumatic exhaust valve, it can be mounted “plug & play” by connecting the vacuum circuit to the Tubi valve, which will be controlled by the control unit and switched via the sport button in the passenger compartment

• With electric valve and valve control unit. This muffler can be mounted both on cars without valve and on cars with sports exhaust, and allows you to have direct control of the electric valve via the APP or radio control. The control unit must be powered by connecting to a fuse under ignition, and allows it to be controlled in 4 modes:

Mode 1 – the valve is always closed. is the default mode, which is reactivated each time the machine is switched on

Mode 2 – the valve is always open

Mode 3 – the valve opens only in case of strong acceleration or deceleration, related to sporty driving. If you return to a standard guide for more than ten seconds, the valve closes again

Mode 4 – the valve opens only on release

If this exhaust with electric valve is mounted on a vehicle equipped with PSE, obviously the control of the valve via the Sport button will no longer work, as it will be replaced by the control in the 4 modes described above.

In combination with this muffler, it is necessary to buy the Tubi Style specific tailpipes, available in different aesthetic finishes.

Second variant produced with GPF – from 2019

At the end of 2018 and the beginning of 2019, Porsche engines introduce the  GPF, the particulate filter in Europe and other markets. The GPF is inserted in series with the catalytic converter, in a single body, whose varying dimensions and functionality require a variation of this component compared to its predecessor, only in markets where the use of this component is envisaged. Therefore, the silencers and exhaust tailpipes remain unchanged, for a modification that is almost invisible to buyers, except for a more “capped” sound, and an almost imperceptible reduction in the maximum torque range.

Commercially, this engine update coincides with the launch of the 718 Porsche Boxster T and Cayman T, a sporty variant that recalls the Touring model launched in 1968, more essential and with sportier trim and calibrations.

As we have explained on the original exhaust system, in all markets including the USA, in which the variant with a particulate filter has not been introduced, all the solutions supplied by Tubi Style for the previous period remain valid on all models, including the new Touring variant.

For the variants equipped with GPF to date we have not yet developed a dedicated catalytic converter solution, so our catalogue offers only solutions as:

Third variant naturally aspirated 4.0L engine – from 2019

Although there has been an ongoing commitment by Porsche to optimize the 718 four-cylinder product, which is a very pleasant and, in many ways, unrivaled sports car in its class, part of the Porsche public remains skeptical about the model. On the one hand for the introduction of the Turbo, on the other hand for the reduction of the displacement in favor of a 4-cylinder often considered too “poor”.
Porsche responds to this type of customer by launching the extreme GT4 version in 2019, which becomes the basis of a line of cars equipped with a 6-cylinder 4.0 immediately very welcome to the public, which gives a convincing response of excellence to this new proposal: these are the Porsche 718 Boxster GTS and Cayman GTS in the new 4.0L engine, the iconic 718 Cayman GT4 and the beautiful 718 Spyder.
The exhaust systems for the 2.0L and 2.5L turbo engines remain unchanged, as well as the offers described above for customizing the Tubi Style exhaust systems.
On the 4.0L, on the other hand, a new exhaust system is developed that develops on two separate exhaust tracts, one per bank, with the catalytic converter integrated into the exhaust manifold, a technical solution in continuity with the older sister 911 GT3.

The GPF Particulate Filters are positioned in the pipe that joins the muffler to the catalytic converters, near the muffler, which offers a one-piece solution with double pneumatic valves at the silencer inlet.
This exhaust solution is certainly more refined and suitable for the high-performance car model, but more difficult to manage in the aftermarket world.
The muffler alone then differs according to the type of model:

• On GT4 and Spyder earlier models, fixing is done by metal bands for both the particulate filters and the muffler. in which the muffler part number 982251053D and the two bodies of the GPF are fixed through metal bands.

• On 4.0 GTS and latest GT4 and Spyder models, fixing is done by means of silent blocks. The spare parts code of the muffler in this case is 982251053E

ATTENTION – the silent block solution was introduced on cars produced starting from March 2020, and also introduced on GT4 and Spyder, but is not reflected in the official technical documentation. For this reason, before ordering the product, a visit to your trusted installer is required to check which muffler is actually installed in the car.

The Tubi Style catalogue offers two different solutions for this model

GPF REMOVAL PIPES FOR PORSCHE 718 GT4, SPYDER AND 4.0 GTS

GPF removal pipes should be used in markets where this is provided. The adoption of this system is not compliant for road use, and is dedicated to track use only. Removing the GPF causes the engine warning light to come on, and the indications we have given on the matter remain valid: on the other hand, on the naturally aspirated engine, the decrease in exhaust back pressure improves general performance, with a significant increase in torque and power, improving also the sound of the car, which is much fuller in this way.

STRAIGHT PIPES EXHAUST FOR PORSCHE 718 GT4, SPYDER AND 4.0 GTS

The muffler is a straight pipe solution, not approved for road use and specific for track events, which is divided into two variants depending on the mounting methods:

• A muffler that can be mounted with steel bands, specific for the Porsche 718 GT4 and 718 Spyder earlier models
• A variant with silent block fixing, for the Porsche 718 4.0 GTS and latest Porsche 718 GT4 and 718 Spyder models

THE NEXT STEPS

Tubi Style wants to further enhance the range offered to 718 customers, and plans to develop the racing catalytic converters with removal of the particulate filter for 2.0L and 2.5L cars equipped with GPF, and the exhaust manifolds with racing catalytic converters for cars with 4L engines.
