What this part changes
The downpipe is the tube that runs down from the turbocharger. This is where back pressure builds up: the turbine has to push the exhaust gases through a restricted section and often a catalytic converter. Making it wider frees up the turbine, allowing it to build boost earlier and more decisively - it is the exhaust modification you feel most on a turbocharged engine.
What changes behind the wheel: response. The turbo takes less time to spool up, and the power continues higher in the rev range. On a remapped engine, this is the part that allows the ECU to deliver what the tune promises; without remapping, the ECU compensates and much of the potential gain remains untapped.
What to plan for
- ECU remapping: essential to make use of the gain and prevent limp mode.
- Without a catalytic converter, the car is no longer road-legal and the engine warning light will come on if no electronic adjustments are made.
- Check the sensor port configuration: single or dual depending on the engine, as indicated in the product page's technical details.
- Removal often requires access from underneath and removal of an engine mount: plan on using a lift or jack stands.
