We have developed the exhaust headers for the 9th Generation Honda Civic 1.8 FB for sometime now. We eventually have the change to bring the car onto the dyno machine. And we have done it again! It is again proven the SUPERCIRCUIT exhaust setup significantly improves the performance of the Honda's R18Z1 engine.
See the installation of the SUPERCIRCUIT headers and the rest of the custom made exhaust system and dyno chart below:
The Honda Civic FB 1.8L factory stock headers shown below.
This is how the exhaust oulet looks like once the headers is removed from the 9th gen Honda Civic FB 1.8L R18Z1 engine.
The Honda Civic FB 1.8L headers vs. the SUPERCIRCUIT catless headers on the left. The SUPERCIRCUIT headers are made with grade 304 mandrel bent stainless steel pipes and full TIG/Argon welded. Even the flanges are machined from 304 billet stainless steel, to ensure perfect fitment and durable too.
The EGR (Exhaust Gas Recirculation) pipe and the original metal gasket on the Honda Civic FB 1.8L headers is shown below.
