I have the same car and went with the corsa longtubes with the no cat Corsa sport exhaust. Everything fits together great, and it Corsa so you know its legit. Lethal I believe had some killer deals on their headers last year for Black Friday!
I know a lot of guys will get all crazy because of this recommendation. But I’m very happy with my catless 2m long tubes. I finished it with a mbrp street catback, but cut out the “H” and used a $60 jones dual in/out muffler in its place. True 3” all the way back. The jones got rid of all the rasp, lessened the drone, and reduced overall volume to a level that’s manageable. The headers may take a few months to arrive, but everything you need is there including o2 extensions, and two pairs of mid pipes so you can run straight 3”, or neck down to stock catback. Paid about $450.
