Exhaust Header vs. Manifold: Which is the Better Choice for Your BMW M54 Engine?
When upgrading your BMW’s exhaust system, choosing between an M54 header and a manifold is essential for improving performance. The key differences lie in the materials and design. M54 headers are made from lightweight T304 stainless steel, while traditional exhaust manifolds are typically crafted from thick, heavy iron. Additionally, M54 headers are longer than manifolds, providing improved exhaust flow.
Exhaust manifolds tend to create back pressure, which reduces engine performance. In contrast, M54 headers feature individual tubes for each cylinder, effectively eliminating back pressure. This design allows exhaust gases to flow freely, enhancing horsepower and torque. For optimal performance and efficiency, M54 headers are the superior choice over traditional exhaust manifolds.

Nice and deep, give the car a nice roar

I’m pretty impressed overall. The packaging was top-notch. Everything arrived perfectly sealed, and there was no damage during shipping.
As far as the fitment goes, the headers were nearly perfect. However, I did run into a couple of small issues. First, I had to slightly modify the engine mount bracket to ensure a proper fit. It wasn’t a big deal, just a bit of adjustment needed. The other issue I encountered was with the O2 bung placement. I had to modify the firewall slightly to accommodate it, but again, it was a pretty straightforward fix and is required with mostly all aftermarket header replacements on these e46’s.
One thing I would recommend is to stick with OEM header gaskets instead of using the ones provided in the kit. The OEM gaskets seem to offer a better seal and fit, and heat protection for the upper plastic valve cover.
All in all, I’m very pleased with the headers. They’re a great upgrade for the E46, and despite the minor adjustments, the process was pretty painless.

Parts came on time and were a quality product. Fit was good.

The manifold is of very good quality and can also be assembled, you just have to cut the thread of the oxygen sensor at the end and the shipping is very fast. thank you
We are very glad that you like our products! Looking forward to receiving your feedback pictures or videos!

They fit good, theses are same designs as any other header for the e46 and if you read any forums you would know you either have to cut down the secondary o2 bung or dent in you fire wall a lil but that it, on these car you only need the up stream sensor so I just unplug the downstream one and left the caps that came on the headers on there just tightened them
Thank you for such heartfelt feedback, we will continue to work on improving the product!
