New F-Series Downpipe for the M235! BMW Changes design as of 07/13 Build!
I have had a few questions and wanted to let you guys know that your new M235s have a new design 4.0" down pipe. BMW changed the configuration on 07/13 so all cars built after that date have the new 4.0" design.
****** 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 if you are interested in getting a set. 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. |

good post. since a member asked me for parts, maybe this might be helpful to others.
BMS already released JB4 and intake for the 2 series. It's been confirmed as well that f30 parts transfers over to the f20 series as well. ER+BMS also has charge pipe for f2x. Versus, Supersprint has both DP and Exhaust. As well as Competition who has 4" DP for f2x. |

is the 4" DP the reason for the more aggressive sound?

You can check some of Justin's threads, he has the ER installed with other supporting mods, this DP from what we already know is true 4" diameter unlike the Super Sprint model which seems to taper off from what I've been told.
Seems to be cheaper too. I should have one arriving soon and will post some additional info when I can, possibly a DIY as well. |
