Shame there is no UK spec video-the OPF makes a big difference here.
I'm getting a Milltek sports spec system fitted on the 30th March and I'll see what it's like with the OPF in place.
If it doesn't cut the mustard, I'll go back for the Milltek downpipe with OPF delete.
I am 99% certain you will be going back for the OPF delete as to my ears the Milltek makes little difference. It's all personal taste but I would probably go with the Remus over the Milltek on the GTI. Only thing with the Remus is I am not keen how you can see some of the system hanging below the rear valance so I would probably feel the need for something like a maxton rear trim to hide it.
Dont get me wrong I like Milltek - I had one on my B9 S5 and it was epic - but they are quite hit and miss (new RS6 system sounds appalling)
It is always hard as listening to videos vs hearing it in person, but this sounds ok to me;
