I am looking at a full exhaust for my 2017 1ss. I was wondering if i had to get the connection pipes with kooks in order to connect them to the corsa system. Can anyone that has done something similar tell me how this goes together?

You have to buy Corsa’s header connection kit

I'm also looking for info on this. The Corsa connection pipes only seem to be be able to fit directly onto the Corsa non catted headers based on the way they bolt up with those plates attached to the header and the connection pipe:



If you got non-catted kooks, there's no way to get that bolt plate on to connect the pipes:



If you got the catted kooks, the length wouldn't match up and they wouldn't be able to bolt on either:



I was thinking maybe you could just take those end pieces of the connection pipes off, but thats where the O2 sensor screws in so that wouldn't work ethier:





I've got the full Corsa catback and planning on getting Kooks catted headers. Based on all this, the only thing I can think of is to cut the ends off the catback connection pipes (because they bolt up directly to stock cats) and clamp those onto the headers? Honestly can't think of any other way to make it work, can anyone else?

So from what i understand, you need both the corsa connection pipes and the kooks connection pipes. I was told you have to cut the kooks connections right before the o2s and the corsa connection pipes will slide over the kooks, then you just clamp it with the included clamps. So i dont think this would work with the catted kooks headers. You might need a shop to fabricaye some 3" pipe to connect onto the cat and then feed into the x pipe.
Good luck!
