Hi Art, I have a silver metallic GT4 and the cap looks great but I got mine for $160, I didn't read it correctly either aluminum LOOK, lol. Anyway I heard a Fabspeed race exhaust for GT4, on you tube, Pure Flat six-sounds look it up. That's the one I like the best so far. Take care Robert/Miami.thanks for your videos
