The REDS 2143 exhaust, paired with the size M elbow, helps gain approximately 30 to 40 seconds of range, depending on the circuit and the grip of the track.

Enjoy a range of up to nine minutes or more per tank with the 721 Scuderia engine and the Tetra clutch system.

This exhaust guarantees a torque increase of up to 5%. It offers precise throttle response at low and mid-range RPMs, combined with smooth and linear performance up to high RPMs, for an exceptional power curve. We recommend using this exhaust with engines in the S range, such as: 721 Scuderia, 721 Scuderia Gen2, 721 Superveloce and 721 Corsa.

This version has been revised to be compatible with base OS engines like the 321 ESTREMO engine.
