How can I improve my Vauxhall Astra's performance?

I recently purchased a Vauxhall Astra and I'm wondering if there are any modifications or upgrades I can make to improve its performance. I want to get the most out of my car, so any advice would be appreciated.

First, I would recommend investing in a high-quality air filter. This can improve airflow to your engine, resulting in increased horsepower and acceleration.

Consider upgrading your exhaust system to a more efficient one. This can improve exhaust flow and increase engine power.

Another option is to install a performance chip or ECU tune. This can optimize your engine's fuel and air ratios, resulting in a noticeable increase in performance.
