Cobra vs Scorpion: Which Exhaust for Your Fiesta ST150?
A head-to-head comparison of the two most popular exhaust systems for the Ford Fiesta ST150, covering sound, performance, fitment, and value.
Introduction
Choosing an exhaust for your Fiesta ST150 is one of the most impactful mods you can make. The two biggest names in the game are Cobra Sport and Scorpion Exhausts, and both offer excellent cat-back systems for the ST150.
Cobra Sport Cat-Back
Cobra Sport is a Sheffield-based manufacturer known for their quality stainless steel systems. Their ST150 cat-back comes in both resonated and non-resonated variants.
Pros:
- Lifetime warranty
- Deep, mature tone (resonated) or aggressive bark (non-res)
- Excellent fitment with OEM-quality hangers
- Polished tailpipe options
Cons:
- Slightly pricier than Scorpion
- Non-res can drone on motorways
Scorpion Cat-Back
Scorpion is another well-respected UK brand with a strong following in the Ford community.
Pros:
- Competitive pricing
- Good sound character
- Proven track record
Cons:
- Warranty terms vary
- Slightly louder than equivalent Cobra resonated
Our Verdict
For daily driving with occasional spirited runs, the Cobra Sport resonated cat-back is our top pick. It delivers a noticeable improvement in sound and a small power gain without the motorway drone. If you want maximum noise and don't mind the volume, the non-resonated Scorpion is a solid choice.
