How can I increase the power output of my Audi 80?

I recently purchased an Audi 80 and am looking to boost its performance. What are some modifications or upgrades I can make to increase its power output?

One of the simplest ways to increase power output is to upgrade the engine's air intake and exhaust systems. This will improve airflow and result in a noticeable increase in horsepower and torque.

If you're willing to invest a bit more, you can look into chip tuning or remapping your car's engine control unit (ECU). This can significantly increase horsepower and torque without major modifications.

Another option is to install a performance exhaust system, which can provide a deeper and more aggressive exhaust note while also increasing power and improving fuel efficiency.
