yeah basically, its called 2 step for a reason...when you put the handbrake on it lowers the rev limit, i think mines at 3500k or something, and then yea, clutch in and a few revs...:angry: When i say the handbrake is on, lifted up about 1cm so the car thinks its on but its not... It does have a decat, but because of the standard pipe work it has a tiny little rasp at about between 3k-3.5k.. You can use it with a cat, but it wont last long, and you wont get flames, but you will get the bangs/pops still Rob
