m40i downpipe
![]() Featured on BIMMERPOST.com is the downpipe on the supra identical to the 1 on the m40i? was not able to find the part number for the downpipe of the supra just the m40i and found diagram for both and they look the same . |

There is this video on YouTube of a 2020 Supra being fitted with an exhaust downpipe.
To me it sounds a little tacky.

rk tunes and boost logic sells them for the 2020 supra ... need a confirmation if its the same part as the bmw dp so i can pull the trigger on one 😁
the G20 M340i has the same dp (same part number) and seems no 1 makes for it a DP so far Last edited by habib86; 08-15-2019 at 02:53 PM.. |

No one has test fit the current b58 DPs as of yet. Unfortunately, I sold my m240i with the DS-1 sport cat DP because it was welded to the Remus exhaust. Debating on spending the $300 for the VR catless DP for the b58 and see if it fits. I'm going to guess it won't but haven't gotten under the car to get a better look. The Supra video looks like the downpipe exits at a slight turn whereas the m240i didn't. Again, might just have to bite the bullet and find out.

"We believe that it will fit but we have not tested the fitment yet." and theres a tune from MHD for the g29 Z4 and a drop filter by BMC so guess im all set 😁 |

Let us know how it turns out! I've been back and forth with performance mods and wheels/tires. Already have issues putting power down so at least new tires are in order IMO before more power.

I'm really surprised that the EU spec m40i uses a vband clamp on both ends, whereas the US spec m40i uses vband only on the turbo side with a slip/clamp on the catback side.

With a cat less DP you will definitely get a CEL. With a sport car DP it can be 50/50. Usually an O2 spacer helps if it shows up
