"BMW E46 M3 Transformed with Insane 10-into-1 Headers and V10 Swap"
Originally Published 2 years ago — by The Drive
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.
