Definitly, even a SOHC (well equiped, all motor) will, but RX-8 has a lot of power hidden by the ecm. I have seen RX-8 with exhaust system, Nology wires, ground wiring systems and even with K&N intakes, but it only feels more noise.... If you want to see something interesting go to YOUTUBE and write TYPER VS RX8, then let me know. Adios
