This is a complete package for a very rate parts kit: A set of true CSL headers for the E46 M3. The size shape and flow rate of the CSL header is identical to the Euro header (both big improvements over the stock US header), but the CSL version is much lighter than the standard Euro headers, due to their metallurgy and thinner wall thickness. These are reported to be roughly HALF the weight of the standard Euro-spec headers. They bolt to the S54 engine using standard hardware (included)
The CSL was never offered in the USA, and only sold in very limited units around the world. While these parts were once available stateside, these become difficult to source about 10 years ago, with supply drying up and or blocked from non-CSL owners around the world.
What's Included:
Qty 1 - Genuine BMW M3 CSL Front Manifold (Cyl 1-3) - 11627833500
Qty 1 - Genuine BMW M3 CSL Rear Manifold (Cyl 4-6) - 11627833501
Qty 1 - Header Install Kit (New exhaust studs, copper nuts, and gaskets)
The BimmerWorld View: These headers go beyond bragging rights. If you're looking for a header to make better power on a dedicated track or race car, we have other options that can make more power (and at a better cost and value). Contact us for that. This CSL header kit is a rather unique piece, and while ULTRA cool and desirable by purists, there's even better full-race headers setups available. That said? The cool factor is off the charts on these factory BMW headers.
Last set available. We searched high and low to get our hands on a set of these in the USA. This was the only set we could muster. Neither the Euro M3 header nor the CSL Headers are available in North America anymore, making this an exceptionally rare find. This is without a doubt the very last example we'll ever have in our hands here at BimmerWorld.
Race Part / Disclaimer: We reserve the right to sell this set of authentic CSL manifolds to either a verified CSL owner, a true Euro-VIN M3, or a dedicated race car in need of a CSL header. This header set will NOT be sold for a US-spec street car. We might make an exception and sell it to someone making Motorsport Wall Art.... but definitely not for a street-driven car of any kind.
This parts kit includes authentic Genuine BMW headers. As these are rare Euro-spec parts they do not come with any warranty (other than safe delivery from BimmerWorld). Professional installation and final tuning (if not used on a CSL) are recommended.
