The VQ is one of the best stock sounding engine/exhaust combos of all time.... never heard anyone call it "coarse" before. Have you had much experience around Z/G's? Cause that statement above is blowing my mind.
Also, OP, WELCOME! Congrats on the purchase, both are nice vehicles, but from an enthusiast standpoint, I think you will be more than happy with your purchase!
