Depo Racing Focus RS Catless Downpipe. In stock cars, the stock catalytic converter is the primary choking point to make power with a turbo. In order for the turbo to spool fast and compress the air for the engine, the exhaust needs to escape freely. If the exhaust stops flowing the turbo stops moving efficiently.
If you new to the Focus RS welcome, I’m not new to making downpipes. My parts are on world record Evo’s and Focus St’s
