Group N line GT2i Alfa Romeo 33 (907) 1.7 16S 137hp Non-catalytic converter
Group N Steel GT2i line for Alfa Romeo 33 (907) 1.7 16S 137hp Non-catalytic
Engine performance is closely linked to its ability to efficiently expel combustion gases.
These group n lines have been designed in collaboration with leading tuning specialists. The shape and, above all, the diameter of the pipe guarantee maximum engine performance by increasing the power and torque.
These Gr.N lines are made with high-quality materials for increased reliability. They are easy to install because they use the original diameter at the mounting point.
Note that FIA CSAI regulations allow a noise limit of 98 ±2 db in GR.N.
The use of group n lines is not permitted on public roads. Therefore, they are not GUARANTEED.
CAUTION: The line must be installed complete, as its components are not similar to the original ones.
Products intended for vehicle modification for competition purposes may render their use prohibited on public roads, insofar as they significantly alter the vehicle's characteristics as specified in the type-approval certificate issued by the relevant authorities (noise level, pollutant emissions, maximum speed, tire dimensions, etc.).
