What is the most important thing to consider when choosing an exhaust system for a Ford Puma?

I have recently purchased a Ford Puma and am looking to upgrade the exhaust system for better performance. Which factors should I consider when making this decision?

When choosing an exhaust system for your Ford Puma, the most important factor to consider is the material used. Stainless steel is highly recommended as it is durable and provides better performance compared to other materials.

Another important factor to consider is the type of exhaust system. A cat-back exhaust will provide a more aggressive sound and a slight increase in performance, while a full exhaust system will provide a significant performance improvement but at a higher cost.

I would also recommend researching and reading reviews on different exhaust brands to determine their quality and performance. Popular brands like Borla and Magnaflow are known for their high-quality exhaust systems.
