For a better torque range and more power.
You want to get more power out of your turbocharged engine?
Then you should start with this Bull-X product!
Downpipes are a significant part for torque range and power in a charged system. They are the connection between the exhaust outlet of the charger and the catalyst. If the diameter of the downpipe ist bigger, the turbocharger is able to lead off the exhaust gas easier and quicker. This has a positive influence on torque and power.
The advantages at a glance:
• the turbocharger is able to lead off the exhaust gas easier, this is the reason for more power
• better torque range, because the charger can speed up faster
• lower exhaust temperature, so the charger and the exhaust manifold is more protected
On this grafic, we want to explain you, where the downpipe is mounted. This example shows a 2-way downpipe for use with an external wastegate.
Note: We would like to point out that it comes with downpipes without EEC approval to an illumination of the malfunction indicator lamp. Thus, there is no limitation in the driving operation.
