I did a lap around the mount a few years ago in my WB. It sounds pretty nice with a 2" twin system and a lukey muffler and the 253 has a mild cam in it. I did a couple of laps and then a nice HSV commodore followed me around for a full lap, with the cam corder hanging out the window filming my old ute. It made me smile that someone in flash HSV reckoned the old wb was worth filming! I gave it bit to of course.
