What do Extractors do? Extractors make it easier for the car engine to push exhaust gases out of the cylinders. With your cars engine running more efficiently, you will notice improvements in fuel economy, and performance.

Do extractors add horsepower?

The extractors have longer individual tubes so that upon where they merge into the cone, one pipe helps suck the pressure from the other pipe via inertia. The increase in efficiency means a cleaner environment and the cylinders result in a significantly improved power production.

Do extractors make much difference?

The benefits of extractors in our opinion outweigh the cons. Although design in manifolds vary and some are better than most, the design of extractors simply allow for the exhaust gases to be more free flowing. Performance gains, better fuel economy, better exhaust note, are all benefits of extractors.
