REALLY need a ko3/ko3s downpipe for mk1 golf

As titled!
I've been in touch with a few places, and I am able to get one through will Skelton who I found through here but he doesn't have any till end of next week, qpeng don't do them anymore and trackslag only do the ko4 downpipe. I know I'm sounding impatient as that isn't that long but my golf is my only form of transport and it should have been on the road for Christmas! 
If anyone knows of anyway of me getting one this week that would be great.
As I said I am being impatient but I just really need my car hence why I am asking, if there is none about then I will be getting one off will next week.
Any help is greatly appreciated, I am going to be getting the trackslag 2.5 exhaust but wanted to order it when I knew I had a downpipe sorted, and as titled it's for ko3s into my mk1 golf!

Thanks in advance for any info!
