Iím sorry to hear. Based on that picture you posted of the supersprint downpipe, they sent you the wrong part. The PN matches their website, but the picture doesnít match what you received. Also, what you received doesnít look like the shape of the Downpipe for our cars (regardless of vband clamp/slip on style).

Honestly, Iíd recommend opening your hood and removing your air box. Look at your downpipe and compare the shape to what you received. If it doesnít match, take pictures and send it to Supersprint customer support. They should be able to send you the correct part

Try RK tunes they have a down pipe for the Z4 M40i US spec. I emailed them a couple of weeks ago and they confirmed availability and price of $400. I still haven't pulled the trigger yet, as I will be parking mine for winter in the next couple of weeks.

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

Thatís fantastic news! Looks pretty darn good for a fitment. Thatís a mighty clean garage bay. Reminds me of the auto hobby shop on Vogelweh in Germany. They make everyone mop their bay after use and wipe down all their tools before the next person can come in and use it.

Canít wait for the sound clips and the dyno results! Iíve 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

Thats impressive! Mustang dyno right? Mustang is usually quite a bit more conservative than dynojet.

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
