Just to anyone with a scorpion decat fitted. After a few days it has a nasty low down rasp which is loud and annoying. Just wondering if it may settle down otherwise it will have to come off. The wizard exhaust prib doesnt help, in full throttle higher speed it sounds nice, but driving off from standstill it scares people and sounds more like something is wrong with the car. Any views from owners with unsilenced decat appreciated. Ayat
