GREAT PRICE @ www.n54tuning.com


Hey guys

I got ER to put together a breakdown of the different configurations of downpipes that BMW has put out. In true BMW fashion they decided to change things up mid model, mid year to make life more difficult for us

Thanks to Fred and Christine over at Evolution Racewerks for putting this together.

Both versions of these downpipes are now in stock so you can PM or email me for more info. etc.. We have set up the site with a drop down menu so you can select your model year accordingly. If there is any doubts about which pipe you have you can always send a pic of the down pipe area and we can help identify the model.

*******



The F Series (1,2,3,4 Series) N55 cars all share the same downpipe. When first introduced, the downpipes had a 3.5" v-band flange inlet on the turbocharger side. On 07/13, BMW decided to change the downpipe. This new downpipe featured a 4" v-band flange inlet instead. Thus, the previous downpipes are not compatible with the new ones.

Below is the breakdown on which downpipe to chose based on production date:

335i (U.S. Spec) - Up to 07/13 have the old downpipe (BM-EXH007) 3.5"

After 07/13 have the new downpipe (BM-EXH012) 4.0"

435i (U.S. Spec) - All 435i have the new downpipe (BM-EXH012) 4.0"

M235i (U.S. Spec) - All M235i have the new downpipe (BM-EXH012) 4.0"

M135i (European Spec) - Up to 07/13 have the old downpipe (BM-EXH007) 3.5"

After 07/13 have the new downpipe (BM-EXH-012) 4.0"

IF THE VEHICLE IN QUESTION IS BUILT ON 07/13, IT CAN HAVE EITHER DOWNPIPE. A VIN# CHECK SHOULD VERIFY WHICH DOWNPIPE IT IS. TO BE ABSOLUTELY SURE, A VISUAL INSPECTION NEEDS TO BE DONE. SINCE THE FACTORY PART# ON THE DOWNPIPES ARE DIFFICULT TO SEE, THE BEST WAY TO CHECK IS TO LOOK AT THE PART# ON THE BRACKET HOLDING THE DOWNPIPE. THE OLDER DOWNPIPES HAVE 2 STUDS GOING INTO THE BRACKET AND ATTACHED BY 2 NUTS. THE NEWER DOWNPIPE HAS 1 STUD ON TOP ATTACHED BY A NUT. THE BOTTOM BRACKET IS ATTACHED WITH A BOLT, NOT A NUT.

Thanks for this thread Mike, just placed an order for my 435!
I was going to order directly from ER but their page didn't have options to choose the exact DP for my particular model (ie 335i, 435i, 135i etc) .
However, N54Tuning.com did have the drop-down menu to specify exact vehicle type and I shouldn't have an issue with fitment.

I know I sound like a broken record, but does "435i (U.S. Spec) - All 435i have the new downpipe (BM-EXH012) 4.0" include the xdrive? lol

It'd might help to advertise the GB in the 2-series N55 area. A bunch of folks with the new M235i would likely be up for it. ER is unique in offering a solution for EWG cars.

On F30 with a JB4 will it throw a code?
On my old E92 N55 it had downpipe fix but I'm not sure if it works for the F30. Thought I saw Terry saying the DP fix does not work in F30's.

if build date is 07/13, how can we determine if we have the 3.5" or 4" based on VIN number?
