The EP Fiesta ST180 Ultimate Cat-Back exhaust system has been designed for maximum performance and power. 

How is the Fiesta ST180 Ultimate Cat-Back exhaust system made?

The Fiesta ST180 Ultimate Cat-Back exhaust system is built from 3″/76.2mm mandrel bent stainless steel. It is fully TIG welded and back purged for maximum strength, flow and reliability. Good flow is essential in a performance exhaust system, it allows the air to flow quickly from the engine and increases power.

Our unique brushed finish ensures your Fiesta ST180 Ultimate Cat-Back exhaust system retains quality and finish. All hanger brackets are heavy duty and fully reinforced. Powerflex bushes are included.

Fully compatible with the OEM catalytic converter, as well as all aftermarket de-cat pipes. The two bolt flange is fully TIG welded from both sides and surface ground for a leak-free seal.

Fitted as standard with a 3.5″ turndown tip, to both the cat-less and sports cat tip.

Sports cat option includes both sports cat & de-cat tips.

Why Buy the EP Fiesta ST180 Ultimate Cat-Back Exhaust System?

Each of our Enhance Performance Fiesta ST180 Ultimate Cat-Back exhausts system are built in-house by hand.

This is a race grade system, so not only does it include our standard back purged TIG welded joints, we also use V-band joints for a fully leak-free seal.

There are many advantages to V-bands:

  • They do not leak
  • They’re fast to assemble/disassemble
  • They will never seize like other exhaust joints (perfect for a track based car that is pushed to the limits!)

As the EP system was aimed at track/race cars, we can include an optional sports cat tailpipe, fitted using another V-band connection. Although unlikely to pass an MOT emissions test, it will satisfy trackside officials and can act as an additional silencer for race tracks with lower exhaust DB limits, which will not affect performance.

A full lifetime warranty is included on all our Enhance Performance exhausts.
