As part of our expanding Fiesta ST180 product range, AIRTEC Motorsport is proud to launch our tubular exhaust manifold upgrade suitable for track or fast road use. A tubular manifold has a massive increase in air flow which could see big gains compared to standard.
The tubular manifold for the Fiesta ST 180 will see best performance gains when used with a stage 3 setup, hybrid or big turbo setups will see the best improvements.
- Stage 1 cars – A standard manifold on a Stage 1 Fiesta will perform perfectly, an upgraded manifold on a Stage 1 car will see faster turbo spool but will not see a huge improvement over standard
- Stage 2 cars – Higher power cars will see faster turbo spool and some power increase of around 3-5 bhp.
- Stage 3 cars – A tubular manifold is a must have for any stage 3 Fiesta! The standard manifold will be finding it hard to release the air with the manifold pressure not being able to cope with the power.
