Stand out with this incredible Tubi Style Downpipe for all Alfa Romeo 4C Coupe & Spider. (Years: 2013 - Present)
- Downpipe: Complete removal of the catalytic converter minimises exhaust back pressure and delivers optimum results in terms of performance and weight reduction.
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.
