My dad had a Monero VXR 6.0 LS2 with the exhausts changed, it was a VERY loud car, sounded amazing tho. Quick for its size.
He now has a Red VXR8, honestly the VXR8 seems a bit faster, i have to disagree with whats written above, i drove it recently, it feels noticably quicker than the 350 and to me, no bigger of heavier to drive at all.
Ill get a picture up of them together when i can.
