Briefing: What's The Performance Difference Between Catted And Catless Downpipes?
Strategic angle: You might expect that catless downpipes, which lack a catalytic converter, would outperform catted ones. But as the old song says, it ain't necessarily so.
Catted downpipes include a catalytic converter, which is designed to reduce emissions. This can impact exhaust flow and overall performance, particularly in regulated environments.
In contrast, catless downpipes eliminate the catalytic converter, potentially allowing for increased exhaust flow and power gains. However, this can lead to higher emissions and may not be compliant with local regulations.
Performance differences between the two types of downpipes are not absolute and can depend on the specific vehicle setup, tuning, and intended use. It's essential to consider both performance and regulatory implications when choosing between them.
