Mono Exhaust System (MES) is a exhaust system manufacturer in Grand Theft Auto IV and Grand Theft Auto Online.

Description
Mono Exhaust System is a automotive manufacturer which makes exhaust systems. The company does not operate any offices or stores in San Andreas and mostly appears as a minor sponsor on racing liveries in Grand Theft Auto Online.

In GTA IV, the company can be seen plastered on Pay 'N' Spray shops in Liberty City. The Vincent in GTA IV has Mono-manufactured exhausts, which could suggest a manufacturing deal between Mono and Maibatsu; similar to Four Wheel Rotation System and the Mule.

The real life influence of the company is not known but its name is similar to MOMO Srl, but this company does not manufacture exhaust systems.
