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.

The kit includes
• Long Pipe Headers
• Rear Muffler
• Secondary Lambda Harnesses and ECU flasher with the specific Tubi Style map.

Installation of this components requires specific instructions not provided in the workshop manual. The instructions are provided in the package or can be downloaded from www.tubistyle.it

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.

ECU REMAPPING OPTIONS - STAGE 1 FLASHER
Tubi Style Flasher is a user-friendly tool that permits both to the workshop and to the car owner to remap the ECU trough the OBD car port. This flasher permits to apply to the ECU a software change that upgrades engine power and torque, turns OFF the CEL light and maintains always open the exhaust valve when a sport driving mode is selected.

SOUND - STRAIGHT PIPE
The straight pipe version guarantees a direct path from the engine, removing all factors which may affect the acoustic tuning.

END TIPS NUMBER AND POSITION - 1 + 1 CENTRAL
The end tips emerge separately from the centre of the bumper.

MATERIAL - INCONEL 625
The component material required to withstand high temperatures. At the technical state of the art, it is used in F1 cars and in the aviation industry. Its excellent mechanical and thermal stress resistance enable the use of thinner sheet metal, reducing component weight.

MAIN PIPE DIMENSION - 65mm
This is the diameter in mm of the main pipe of the exhaust system.

CATALYTIC CONVERTER REMOVAL - 300 CELLS
Race catalytic converters have fewer cells than standard factory systems. This reduces exhaust back pressure while still cutting pollutant emissions and boosts power 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.

GASOLINE PARTICULATE FILTER - REMOVED
To reduce back pressure on the exhaust and increase noise output, this component removes the standard GPF.

NOTE: Sports catalytic converters and bypass pipes do not have type approval and are not legally permitted for use on vehicles manufactured after 1st March 2001 in the United Kingdom. They are not MOT compliant and must not be used on public roads. These components are intended for race and track use only. If you are located outside the UK, please consult your local laws and regulations to ensure compliance.
