Gen 5 Corsa exhaust on Gen 3

[04BlackSRT10]

The gen 3 I bought a couple weeks ago has a terrible Magnaflow exhaust on it. Because the car also has aftermarket headers (dealer I got it from wasn't sure of the brand) and no cats, it has an unbearable amount of drone. I've read that Corsa exhausts are the most drone free, and I would like to keep the headers and catless mid-pipes. A gen 3 Corsa costs about 2300-2500 bucks, while a Gen 5 Corsa is 1600-1800. Is the exhaust on the Gen 5 the same length as the gen 3/4? It seems like it should be easy to get the Gen 5 Corsa and toss it onto my Gen 3. I know the exhaust tips are oval on the Gen 5, but it seems like they'd still fit within the exhaust hole on my car.

Pretty sure it's same length. If not, damn close.
