Hey guys. New here, don’t know a lot about cars, but I just bought a 2016 VF Calais V 3.6L. And I was interested in the exhaust sound and how it differed greatly to the newer 3.6L V6 RS lift back that I hired last week on holidays... the RS had a great sound when the engine started and under moderate to heavy acceleration... however my VF sounds very plain and underwhelming... what’s the difference? as it seems to have the same engine(?) and what does it take to make mine sound like that RS? Also, just out of curiosity, how does one choose a muffler/exhaust, as in, how do you know what it sounds like before you purchase and install one at an exhaust shop? Sorry if these questions are just plain dumb.
