Have anyone tried fitting the akrapovic exhaust from the 435i on the 428i?

Yes, also knows as the golf tee mod. Not much difference in sound but it results in annoying drone on the highway, at least for me.

What? Golf tee mod is when you disable the exhaust flap, not changing the exhaust system..

Did a test install on the car last week.

There are some problems that needs to be sorted out, first of all we discovered that the exhaust hanger on the right side is a different part number on the 428i and the 435i, so we installed the original exhaust again. I have ordered the 435i part, but it had to be sent from Germany, so have to wait a couple of days for it to arrive.

The exhaust valve had a different angle on the axle that connects it to the flap than the original exhaust, so we could not install it, but I was planning to leave the valve open anyways.

The exhaust did also seem to touch the rear axle carrier, but I think that it will clear it with the new hanger. The tail pipes are a tight fit into the 435i M performance diffusor, probably because of the large size of the tips!

Anyways, we did find out that we will make it fit, but it might need a slightly modification

Haha, working long days + it's raining, so not so fun to make a video in the middle of the night with pouring rain

Will make a video as soon as I have time, but the exhaust is still loosening up and changing exhaust note

Bump! Really interested in this!

Mate with a 911 GT3 said the best sound of an exhaust is only achieved after doing some hour-long autobahn runs at 200+ km! It does make quite a difference actually!

Just a small video clip of cold startup! The sound does change noticeably when the engine is warm, and it is a completely different sound when in sport even though the exhaust flip is open all the time.

I hope that I will get a opportunity to make a real video/sound clip soon
