No same for all.

Factory system needs to be cut behind secondary CATS in US or OPF in EU.

M2C exhaust is identical except we have OPF where you have Secondary CATs.

Hi guys,
For now milltek is only option for equal lenght exahust for M2C, and since other manufacturers that are coming up with new systems are in US. Probably our only choice if we want to keep OPF. I tried to cotact Remus to see if they are willing to make something, but no reply.
I have tried to find some clips of m2 with milltek equal and opfs, but other than teaser clip on milltek instagram, no luck.

Thanks.... They said the length of it does not look right 🤔

The piping needs to be slightly different for the OPF which may be the issue. The exhaust pipe runs down the edge of the OPF, on the secondary cats it goes down the middle. If you compare the underside of an EU/US car you will see the difference. From other posts i've seen the Miltek needs some welding to fit on US cars.

Side note, but OPF's are so lame. All modern EU cars are ridiculously choked by their exhausts.

Yes

I think that will be better anyway since there will be no cutting to the stock exhaust

Awesome, do you plan to go with the straight or the high flow cat's? I'm curious to hear both!

I'm going to put mine on shortly but I'm hoping I don't need to get that delete pipe, I'm based in AUS we have secondary cats in place of the OPF/GPF, although I'm a bit worried, hearing read that some people are still getting drone.

Pretty annoyed my Turner Motorsports Downpipe did not fit,





I was initially going to chop up my stock exhaust but I ended up ordering the Large-Bore Downpipes + Delete Pipe with Hi Flow Cats

Secondary cats will be in place but replaced with a 200cell but yeah we'll see how it all works out, if its still raspy, I'll likely install some resonators or something.

pay attention when installing the downpipes. The longest one tends to touch the subframe and so when turning it will be touching making noises and fibrations. keep it away from the subframe as much as you can

Thanks for the tips, I ended up returning the Turner Downpipes as the alignment was way off, I have now ordered the AR design downpipes with a resonator so fingers crossed it'll be done soon.

I just weighted the OEM exhaust and it's 36.2kg, so about 6kg saved with the Milltek.
