Active Autowerke Performance Headers - E46 323 l 325 l 328 l 330
A dyno-proven source of unrestricted power.
It’s simple, really. Swap the factor’s highly-restrictive headers with integrated cats for our ceramic-coated headers with cats below, and watch the performance climb.
To see what we mean, just take a closer look at the factory manifolds:
- The exhaust catalysts are situated right against the cylinder head, causing extreme heat build up.
- Cylinders 1-3 and 4-6 each channel through to a single restrictive pipe
- These characteristics create extreme heat thanks to an inherently bottleneck design
Active Autowerke’s Performance Header system is designed to eliminate this problem without compromising durability. The factory exhaust catalysts are removed in the process, making this solution suited only for off-road race applications. Optional low-placement cat units are available to help maintain emission standards, but please consult your area’s regulations and laws before installing these racing exhaust headers.
NOTE: Please specify if model is a BMW 323i, 325i or a BMW 325i, 330i.
