Euro Z4M Exhaust
Gent's, I bring to you yet again a nice set of Euro Z4M headers and cats. CSL headers and euro z4m cats can yield gains of about 20RWHP to the S54 engine. Price includes shipping/wrapping/tracking. Photos will follow ASAP.

-US Z4M has two sets of cats. The primary cats in the headers and the secondary cats in the section 1. The US Section 1 has smaller cats as they were intended to be secondary cats.
-Euro Z4M only have a set of primary cats in the section 1. Euro section 1 has the required bungs, so it doesn't require modification. For anyone wanting to buy headers that are not familiar with Euro Headers and Euro Cats (section 1), here's a summary of what I learned when researching mine. I hope it saves someone the time I spent. CSL and Euro headers CSL and Euro headers are very popular because they don't have the additional set of cats built in that US cars come with and give a nice HP bump. They also sound great. -"Euro Headers" refer to the European M3 headers. They are fully compatible with Z4Ms -"CSL Headers" refer to the Headers used in the M3 CSL and the European Z4M. If you want the authentic headers that came with the Euro Z4M (and legendary CSL), you want the CSL headers for sale here. There are some slight differences between these and the Euro Headers, including being lighter. Most people run Euro headers because CSL headers are more expensive and harder to find. Euro Section 1(Cats) Euro Cats are very sought after because they eliminate the need to modify your US Section 1 to accommodate Euro or CSL headers. They are rare because although we can use the Headers from the Euro M3, their section 1 doesn't fit. So compatible "Euro Cats" only come from Euro Z4Ms. -US Section 1 To run either Euro or CSL headers without throwing CEL requires the US Section 1 to be modified. You must add bungs for O2 and EGT. They need to be cut and have the bungs welded in. US Section 1 contains smaller cats than Euro section 1 because they were intended to be secondary cats. -Euro Section 1 These already has the necessary bungs as they were designed to run with the Euro and CSL headers. No modification/welding to section 1 means less headache and less chance for something to go wrong.

HAHA I was actually referring to the title without reading the body of the post which said Euro exhaust and I automatically thought of exhaust cans.

I don't always make productive posts
But when I do, I make sure they are in obscure FOR SALE threads I'll try to make a proper post in that section later that people can add to.

Probably some dumb questions but please humor me. Is there any advantage to the Euro CSL headers and section 1 than say a SS header setup that also removes the secondary cats? Performance, cost, O2's, CEL's?
What I'm trying to gauge is the cost benefit/hassle factor of each setup before I make a decision. If I go to Realoem and pull a a Euro spec MC, will that show me the part numbers and cost of the Euro CSL setup or was the CSL set up an upgrade? |

Running a SS setup with no (primary or secondary) cats -Better performance (less cats are always better) -Worse smell (running no cats can be toxic) -Will have to deal with CEL. Either live with it or get a tune that ignores it. I'm assuming you won't be attempting to smog. Running with Euro headers/Cats -Still better performance than stock US cars (deleting a full set of cats) -No smell (big primary cat. This is the OEM euro setup) -As long as install is done correctly, your car won't know that it's even modified. Will still pass smog.

Thanks for education. So on the CEL's, according to RealOEM the Euro headers have one "Lambda" probe in each header while the US has 2 - before and after each cat. What happens with the extra probe? The US secondaries versus Euro primaries look similar. I assume the difference is that the Euro are high capacity.
Input from anyone would be appreciated. |

You have a pair of pre cat and post cat sensors in US Headers because the cats are in the header. For the Euro headers without cats, those post cat sensors now plug in behind the cat in section 1. Euro Section 1 has the bungs for these sensors. The US section 1 does not. If you get JUST euro headers, you have to modify the US section 1 so you can relocate those post-cat sensors. If you get Euro section 1, they plug right in. |

I created this thread in exhaust section so we can move this discussion over there. When you're ready to get headers and/or Euro cats, Donovan is the man to contact. Great seller.

I also bought CSL headers and Euro cats from Donovan. I've been running them with no check engine light for over a year now. I also passed the sniffer smog test here in CA. These are a cool add on for those wanting to upgrade yet keep an OEM look. It passes Cali visual with no prob.
