The Fiesta ST is one of the most successful small hot hatchbacks ever. And because it's affordable, many buyers like to do at least one mod, with the exhaust usually being the target.
Seeing as we live in the DIY era, we thought it was best to look at how both a custom exhaust and cone air filter are fitted. Even if you don't install them yourself, videos like this will give you some idea of what to expect and perhaps help you make an informed buying decision.
Milltek is easily the most popular Ford exhaust, with this editor still remembering the sweet-sounding 190 horsepower setup for the first-gen Fiesta ST, which had a 2-liter engine. Nowadays, the hatch has 3/4 the displacement and number of cylinders but probably sounds better.
Fitting a sports exhaust requires the pipe to be cut at a pre-determined point. The Milltek system is then connected using a 60mm to 70mm converter clamp. The aftermarket muffler has a butterfly valve, just like the stock one. The company also offers several types of tips, including carbon and burnt titanium.
By comparison, fitting an induction kit is more of a job you can do yourself because it requires no specialist tools or access to a ramp. All cars have an air filtration system to stop debris from entering the engine. All you're doing is replacing the stock one, which is made from cardboard to improve the induction noise and maybe gain a couple more horsepower.
This YouTuber opted for something called a Stage 2 C:Performance Enhanced Intake System that costs just £116.25. To install it, you'll first have to remove the stock air box and install a metal bracket which supports the cone filter. You will also need to swap over the mass flow sensor taking care not to damage it in the process.
