Was thinking of a YS 182 system. What have other people gone for? I don't want it too loud at motorway speeds, when booting it, it can be as loud as armageddeon though.
I didn't pay much attention to all the different exhausts that were present at the recent meet but none sounded too mental, or at least none seemed to bear any resemblance to the bits of guttering that the kids around here attach to their cars that make your ears bleed and startle herds of wilderbeast to stampede across the savanah.
