I may be wrong but I believe that's only on the e89

What’s that disconnecting?

Operation of the flapper in the exhaust instead of doing the golf T mod

Just looked under back end and it looks like you cant do the golf t mod on the 2003 model z4

Just seen this mod, why do they call it the golf t mod and it looks like a 3/16 4.7mm rubber blanking cap, just looked on the net and can’t see any so justed wondered, I ve have an incoming 35i and thought ummmmmm sounds fruity, Has anyone done this mod??? and if so any not effect on engine, running or warning symbols etc,

Hi frankie
Think they originally used a golf tee to blank the tube off once disconnecting? People use different things now like capping sleeves etc , I’ve done it on mine now for about a month, nothing happened to engine or any lights , have heard if you disconnect the power rather than the pipe underneath it CAN throw a ghost on the computer?? Hopefully others will confirm or deny for you. It sounds better, but personally still putting a different exhaust on , worth a try before spending cash on a different exhaust though for sure

E89 only. The E85 doesn't have any of these valves in the exhaust for noise reduction, so it's effectively the same as the "modded" exhausts anyway

Yep , just as the guys say this is only for the e89
As frankie said about a 3.5i purchase
i have an e89 3.5i , think there are other threads about the golf tee mod somewhere on here .
Some say it doesn’t make that much difference, some like it , it’s such an easy thing to do it’s just worth a try to see if it’s for you
