Alfa 4C Novitec Stainless Steel Downpipe

Stainless steel catalyst replacement pipe for all Alfa Romeo 4C (960/961)
This pipe is optimized in both backpressure and exhaust flow and comes as a replacement for the original 4C catalyst.
Only available in combination with the Novitec ECU PowerECU NT2 CC or NT3 SC!
For the PowerECU NT2 CC (Con Catalizzatore) the Novitec 200 cpi sport catalyst is mandatory.
The removal of the original catalyst reduces the (radiant) heat in the engine compartment and increase the performance by approx. 6 bhp and 12 N m.
This replacement pipe is not street-legal in some countries!
