F30 B58 Downpipe Compatible with G20 b58?
Hey everyone, I have my old catless downpipe from my 340i. I just purchased the m340i and was wondering if its the same fitment. I cant find any evidence that would tell me otherwise.

I decided to just try the install and it went very smoothly and it's a direct fit! Whoever plans on using their old downpipe worry no longer! Perfect fitment with no issues |

However the model number is not which would confuse a lot of people including myself. Installation went super smooth and o2 sensors were identical to the oem catalytic converter. 4.5 inch diameter and exact fitment to my oem midpipe. |

I did not :/ I'll be more than happy to record a couple cold starts and high revs with driving as well. |

Awesome! Hopefully I can use my CG Precision DP. Bummed about not being able to swap in my 437M

They fit 100% fine. Some downpipes don't have the clamp needed to perfect fitment, but yes the f30 b58 downpipes fit g20 m340. I know because I sold my Catless ER downpipes to someone with g20 m340 and they fitted it fine the next day no problems.
