What is the best aftermarket exhaust for a Ford Fiesta ST?

I recently purchased a Ford Fiesta ST and I'm looking to upgrade the exhaust for better performance and sound. Can anyone recommend a specific brand or model that works well with the ST?

I've had great experience with the Borla exhaust on my Ford Fiesta ST. It adds a nice growl to the exhaust note without being too loud.

I would highly recommend the Mountune exhaust for the Fiesta ST. It's specifically designed for this car and provides a noticeable increase in power.

I've heard good things about the Magnaflow exhaust for the Fiesta ST. It's a popular choice among owners and offers a deep, throaty sound.
