Ive owned and driven a fair few 4age's (Blue tops, Red Tops, Silver Top 20vs, Blacktop 20v's, 4agze's). and IMHO, the GT86 sounds like its not quite working anywhere near as hard....
the 4age always sounded completely strung out when thrashed... it seems the GT86 takes it in stride imho...
Which sort of sucks, I like the sound of my engine screaming like its about to pop
