BMW E46 Exhaust Headers (M54/M56)

*Headers will currently ship with MLS gaskets for head flange surface only. No bolts or gaskets for the "cat-back" section will be included. We recommend using Elring PN# 18107502346 for the missing gaskets. Thanks

If you’re building an M54/M56 car and want to produce the most power N/A or supercharged, these are what you need.

Cheap headers often have avoidable fitment problems: O2 bung placement that hits your firewall, interference with the motor mount arm, and a fight to make everything fit. These are made to bolt on cleanly and keep everything where it belongs, so you get the performance benefit without the usual fitment compromises.
