good question.....we has been experience before.it will be depend to the installer how there do it. but the correct way is arm the alarm then the engine still running after just switch off by the timer.
Does anyone know whether the extractors for the VQ35DE can fit the VQ25DD of the 250GT? Hunting around for an exhaust system for my car, and so far the easiest option is to use a cat-back exhaust for the 350Z.
