What's the use of an exhaust cardr?
The role of the turbo exhaust system is to reuse the exhaust gas energy that passes through the exhaust turbine. This energy is then used to drive the intake turbine that compresses the air which is then cooled by an air/air exchanger before entering your competitive engine. Therefore your engine breathes more, it accepts more gasoline and therefore it takes more power.
