I recently purchased Milltek race system for M2 Competition. This system is OPF/cat back.


Here is short clip once warm.

That’s the system I want - do the valves work the same as the OE exhaust?

I assume when running in Efficient mode it still sounds a lot better than the standard exhaust?

I’m having to use sport plus with mdm to get any decent sound from the car, hoping I don’t have to with the Milltek!

The car is slightly louder than stock in "efficient" mode.
For decent sound, I'd recommend "sport" or "sport plus".

I experience no drone on highway.

I do not disturb neighbours on cold start either. It's win win for me

Sounds like the one I need then, cheers for posting.
That’s the first one I’ve heard with just the OPF back system.
Even Milltek themselves don’t have a sound clip!

I have more videos to come soon. Weather has been terrible. Trying to convince a camera man is also a small issue

I just got this exhaust, it sounds really good. Some modifications were needed for US cars.

I will attempt to record a video in a few days. I really like the exhaust sound. It provides a deep tone with no rasp and not super loud. I can hear it inside the car well enough to enjoy it. My short trip on the freeway did not cause any noticeable drone.

First I had to cut the pipes after the secondary cats. Once the exhaust was fitted the pipes did not line up. The milltek pipes were to far to the right to mate with the pipe on the right side. I then had to cut the little brace bracket piece that separates the two pipes coming from the downpipe. I also had to remove the 2nd little bracket that separates the two pipes further up. This allowed the pipes to spread enough to mate with the milltek. The milltek was then welded. The rest of the system fit fine. Its hard to explain without pics but you just have to cut some brackets in order to spread the pipes coming from the downpipe. I had the work done at a muffler shop for 160 usd.

Hey, would you be able to get me a sound clip? I just did the purchase then I found this post, a bit worried about fitment since this is the first exhaust mod I've done on a car.

Don't worry to much about the fitment. Any muffler shop can make it work. I have a sound clip on my phone but it sounds different in person. Not representative of the sound.

Don't worry to muvh about the fitment. Any muffler shop can make it work.
That's good to hear, did you get the race one? A sound clip would be awesome.

Maybe because the miller is designed on a UK car with OPF, possibly the pipe centres differ slightly to a non EU car with mid cats instead of OPF?

Anyhow, glad you like it
