It seems like that should work fine, but we won't know until you try it out!

Picture of the mock up I've rigged up to try to test the fitment of the shorties before I put them in:

Hmm, this picture in the 330 diagram looks just like the M56 325, but there's no #2 on the list:

With the cat placement rules of my autocross class, it would be a very big deal to me if there is a 330 or ZHP that came with these secondary cats, can anyone confirm? Would it have to be SULEV to be sold in CA?
That's the European part. Select your car, but instead of 'USA,' tick the 'European' option. Should allow you to find the part number for #2.

And nice work on the shorty headers. Looks really good.

Only SULEVs came with the secondary cats. Only 325s destined for CARB states were SULEVs.

I believe the S50 headers are very big if you don't plan to do some head work..
Is the M52 E36 header the same as M52 E39/E46..??
I believe a M52 header with a pair of 200 cell race cats would be good into a M54.. and the car would pass emissions and if you fit the 02 sensors correct, no CEL will appear.. It's a good low cost mod..
What do you guys think..??

Previous owner was a 523i. They came up real nice with a quick rotary wire brush. Should get some nice gain from not having those cats right there.





I also bought M52 headers Dan..
Can you post a video? I wanna check the sound..
I also plan to install 200 cell metal cats..

so, just an FYI, the Turner E36 "shorty" headers do NOT fit in an E46 engine bay, they're too tall and hit the frame rail.

So I'm going to try modifying E46 M3 headers next... [Edit] The M3 headers mated to an M54 flange will contact the transmission.

The BMP E36 "Shorty" headers DO fit, but are kinda hard to get bolted up, and don't fit quite like stock E36 M52 headers.

The M52 headers fit well and bolted up really easily, but killed low end power.

The M52 headers that i bought were from a 528 E39..
They look like the ones above in Dan's pic..

S50 headers

Am I right in thinking that the s50 headers are 2.5 inch diameter and that the section they couple up to underneath the car is 2.0 (maybe 2.25 inch) diameter? This would create a step in the exhaust system. Would this not be detrimental to gas flow? I was thinking of fitting a set of S50 headers as well but I then realised about this step and am now thinking of Going with the M52 headers but I don't know what diameter they are and whether or not they would create a step also in the exhaust system?

Thanks
Al

I think you should just try it out. The step is really only detrimental at the merge, because that's where all the power is created. The rest is just volume and sound choice.

That's why i went with the M52 headers.. The S50 looked very large to me and i didn't want to lose any low end torque (i also don't plan doing any headwork in the future).. I ve ordered magnaflow 200 cell metal cats to pair with the M52 headers.. (custom x-pipe, oem resonator and custom muffler).

S50 header 6cylinder pipe - stops at gearbox. Doesn`t fit.
Need to remake 6th pipe, but if you remake it, you don`t need OEM S50 manifold.There`s then no sense of him.

Already bought s50b30 manifold and tried to install on m52tub28 @e30.lv - failed. without remaking.

I've fitted the s50 headers to my M54b30 engine, they fitted with very little modification. I will provide full details of what I did if anyone would like to do the same. Just very busy at the moment.

Al,

I'd love to hear some videos of your setup. In for the details.

What modifications did you do?
I bought S52 headers (with 02 sensors on).. I know that i have to mod the end of the header to pair with the oem M54 cat back exhaust. What other mods are required?

Does anybody know if i can remove these bolts?
Are they there for any reason?
Iam asking cause i have new oem M54 gaskets and the gaskets touch the bolts..
I also have M3 E36 gaskets but i prefer the M54.. They seem to prevent better the heat to the valve cover.. compared to the 36 M3 gaskets..
