Tubi Or Not Tubi?

What child has not dreamed of racing a fast car while making motor sounds with moist lips and heaving lungs? Buying a Ferrari fully satisfies that dream but many yearn for more roar. Aftermarket exhaust systems from manufacturers such as those from Tubi, Capristo, Borla and others promise added ear joy. But do these pipes risk a shift from "cruise" to "bruise?" Can these radical pipes harm our ponies?

The answer is yes, but why? A Ferrari exhaust system is much more than a pipe with audio resonance. These systems are the result of thousands of hours of careful research, design, balancing and testing. Air pressure within the pipes has a significant effect on how fuel is burned, how power is produced and overall reliability.

For instance, when a cylinder detonates fuel, an explosive pulse is pushed through the exhaust. The speed of the pulse determines your engine's high-end and low-end torque. The speed also determines the so-called "scavenging effect" which affects horsepower and torque by maximizing fuel burn efficiency.

Any change in the volume and dimensions of a factory exhaust system may affect horsepower and torque. However, these changes may be accompanied by undesirable consequences.

Ferrari introduced a revolutionary modular exhaust in 1999 on the 360 Modena and employed it on all models thereafter. This exhaust features an ingenious valve, controlled by the engine's ECU computer. The valve modifies the volume of air in the pipes as part of a complex combustion formula that varies in response to the driver's demands.

A Ferrari ECU, responding to the pressures in an aftermarket exhaust, will try to compensate for the altered parameters, but eventually it will not be able to manage effectively. The only way the engine can respond is to illuminate the check-engine-light. However, this may not occur immediately. Engine damage may result before the owner is aware of the problem. Consequently, the installation of aftermarket exhaust systems will void the manufacturer's warranty and any POWER coverage programs.
