That is a subjective question:
Not everyone would give the same answer.
Seeing that you have the 3.6 V6 I would say that the magnaflow Dual exhaust meant for the V8 sounds good.
There is someone on here that has the gibson rear muffler for the 3.6 which I don't like the sound of but other will say different.
RIght now I am running the OEM Hemi exhaust on my V6 and that hardly makes any noise.
Be the guinea pig and install the corsa on your V6 so we can see what it sounds like.
