Race catalytic converters have fewer cells than standard factory systems. This reduces exhaust back pressure while still maintaining the operability of the catalytic converter, and improves perfomance and sound.
The straight pipe version guarantees a direct path from the engine, removing all factors which may affect the acoustic tuning.
EXHAUST VALVE
PNEUMATIC
The exhaust system is complete with pneumatic valve to replace the standard pneumatic valve installed on the car. Control of the original valve is still provided.
END TIPS DESIGN
OE
The muffler must be used in conjunction with the original exhaust end tips.
