it has the hp of the euro spec (dyno shows 334whp) and the exhaust system of the us spec so the dp wont fit so us spec z4 owners any 1 know a company that makes dp for the z4 m40i ? Last edited by habib86; 10-07-2019 at 10:37 PM.. |

Honestly, I’d recommend opening your hood and removing your air box. Look at your downpipe and compare the shape to what you received. If it doesn’t match, take pictures and send it to Supersprint customer support. They should be able to send you the correct part |

Downpipe that they resent fits like a glove ... huge thanks to supersprint total pros in customer service
will be doing a dyno run later as we finished the car kinda late but did a stock run and the it made 334whp butt dyno says it feels way faster now after the dp and tune sounds insane ... highly recommended mod for any B58 engine out there will be talking sound clips later Last edited by habib86; 10-24-2019 at 04:39 PM.. |

Can’t wait for the sound clips and the dyno results! I’ve been itching to mod the car but other priorities at the moment. |

the B58 is a monster as it made 374whp on 91 pump gas and made 402whp when mixed with ms 109 (50/50)
only mods are dp and drop filter and a tune (still not finalized) it pulls like a cat on fire and sounds like a ak47 when it pops Last edited by habib86; 10-28-2019 at 09:14 AM.. |

Awesome! Take a video!! I'm also considering downpipe just worried it will be too loud. Does it get significantly quieter when you put into comfort mode?

Sounds good. The bangs are loud, but not over bearingly consistent like the Supra with tune and DP. Need to do some drive by videos or attach the camera to the backside while driving
