Header options for RHD N52 cars

Hi all,

I've been reading the various AA and SuperSprint header-related posts with jealousy. I own an Australian market, right hand drive 125i with an N52 engine and apparently the SS and AA headers won't fit and I can't find another off-the-shelf option.

Have I missed something in all my searches? Is there a manufacturer who makes headers for RHD E82s with the N52 engine? It seems strange that the UK guys don't have a solution (as far as I can tell).

I asked ARMA Speed if they have anything for RHD E8x series cars with N52 engines and they replied that they have a full system, including headers, for the E87 130i. Do headers from 130s fit 125s?

I know I could have a custom set made but I'd prefer to buy a product with proven results. Plus, there doesn't seem to be any exhaust 'craftsmen' left around where I live. The internet isn't good for everyone it seems.

Any suggestions are welcome.


Cheers
Michael

130i parts fit 125i. It's hard for us to relate because we don't have any RHD Cars here.

So for US LHD models, a 130i header will fit a 128i without modification? If that's the case then there is hope that the same will be true for RHD 130i / 125i.

Does anyone have experience with ARMA Speed? They have the only RHD E8x (130i) header I've found so far and it isn't cheap at $1,800 (on sale now for around $1,400) so it would want to be good.

Werd. Also, stock manifolds with the cats removed is an option.

Cool, thanks Axiom.

I'm not giving up on the headers yet but the de-cat option could be a last resort.

Are there any pictures of the RHD models and the header area? The mapleridge headers literally take up less space than the stock headers, so i'm willing to bet they'd fit.

Assuming RHD has the same headers are LHD at least.

No idea. We don't have the N53 in any form in the US.

I suppose the stock 130i and 125i manifolds will be different so I can't compare BMW part numbers to check compatibility.

Maybe ARMA Speed will give me a discount to prove their 130i headers fit 125is as well.

I bet the part numbers are the same, there should be no difference with the exception of the software.

I don't think the software will affect anything if you keep the same sensors. this is interesting though as one can make a custom set of headers from a used set of oem headers

I wouldnt use ARMA headers unless there was no choice. Bceause of two things - their price is almost SuperSprint, next their design features strange shapes where collector pipes look like this (). As if its some resonator.

Contact Schiedmann about their headers, they are cheap and more local to you than ARMA

Top work gents - thanks!

I did a quick google for Schmiedmann headers and the results were mixed. Poor fitment being a common thread.

I'm not sold on the ARMA Speed ones by any means, particularly since I can't find any dyno results for that particular manifold.

It's a bit frustrating knowing there are good gains to be had, as shown with SuperSprint product, but no proven RHD options.

I'll some more reading on the Schmiedmann headers.
