Worth the Wait!

They took a long time to develop, but the Hyper-Flow Pre-Cats and Pre-Cat Race-Pipes are worth the wait. Drastically improved airflow means a huge bump in horsepower as well as a broader power band. Available as a emissions-legal Pre-Cat or as a Pre-Cat Race-Pipe, there is no better way to free up the power hiding in your flat-12. There is virtually no difference in airflow between the two, so either will give you the maximum amount of exhaust flow and sound that your TR can offer.

Hyper-Flow Catalytic Converters offer your Ferrari maximum legal air flow for Maximum performance. Our stainless steel metallic core with its exclusive treating process easily out flows even the best ceramic units, while maintaining full OBD2 compatibility. Even 100 cell ceramic “race cats” are no match for Hyper-Flow converters. In most applications, our core is capable of more air flow than the factory pipe size allows.
