Wulfchiptegnik™ can supply custom performance downpipe solutions for a variety of vehicles.
The downpipe section of an exhaust system connects the headers or exhaust manifold to the catalytic converter(s). For most vehicles, the downpipe section is essentially incorporated with the catalytic converter section, and since there’s very little performance or fuel economy benefit to replacing a modern catalytic converter, most vehicle downpipes are never given much thought. However, on a vehicle equipped with a turbocharger, an after-market downpipe can offer a significant improvement in performance. Because a turbocharger is essentially a pump, it’s important for the pipes entering and exiting the turbo to have unrestricted airflow. On many turbocharged vehicles, the exhaust pipes coming in and out of the turbo contain numerous bends. If these pipes are bent using a cheap, crush bending process, they can restrict exhaust gas flow in and/or out of the turbo. By reducing exhaust gas restrictions, the turbocharger can spool up more quickly. Faster spool-up times mean more power and/or better fuel economy.
