>1. What can be the reason for high exhaust pressure
Most likely is an obstruction in the exhaust path. Potential obstructions include fouling of the HRSG tubes, improper damper or stack closure position (if dampers or stack closure are present), catalytic converter fouling (if you have these). What kind of fuel are you burning?
>2. What impact it can cause on Gas Turbine performance.
It will definitely have a negative impact on performance - both output and efficiency.
