I've always wanted to do this, I was just wondering how you guys would do this, I was going to hook a coil up to a spark plug in the rear of the pipe and see what happens and if it didn't flame, then I was going to take a washer fluid thing and put in something in there....and mist it in the pipe before the plug. I don't know what do you think of this??? anyone seen this done or tryed it? I got hooked when I saw a CRX shoot the flame out of his tail pipe on main street at night....
