Since 1989, F1 engine design has evolved from V12s to V10s, then V8s, and now V6 hybrids, driven by regulations aimed at reducing costs, emissions, and increasing technological innovation, with each transition reflecting a balance between power, efficiency, and practicality.
The Driftworks V10 E46 M3, originally built with an S85 V10 engine from an E60 BMW M5, has been upgraded with custom 10-into-1 headers from Celeritech. These headers not only aim to increase power by optimizing exhaust gas scavenging, but also create a unique and higher-pitched exhaust note. The car, which was recently restored by Driftworks, features a five-exit exhaust system and offers the option of an open exhaust dump. While power gains have not been measured yet, the focus of the upgrade was on style and sound.
