Ok, so here is my problem. When I shift the car into reverse, and start going backwards, I hear this annoying noise comming from like the right side of the car, and is much louder outside than inside of the vehicle...what could this possibly be? Also, when Im driving down the road, i hear this squealing noise which sounds to me like it is a thin peice of metal and sometimes I dont hear it...What could this be?
Also, I am in the process of upgrading my 00 Civic Si to an external coil..any diagrams? I know how but a diagram is always beneficial...

I live in WA, and might w3anna sell my low mileage ride..oo civic si, b16a2 stock internals, almost perfect compression, new platinum plugs, msd high conductor spark plug wires, msd balster 2 coil, sci ignition box, msd distributor cap...with a dc sport header, high flow cat, can in the back, niice cd player and sound system, niice interior, ok exterior, and is electric blue pearl, sitting on 17 inch enkei rims wrapped with 100% new toyo proxes. I have oem springs on it too..absolutley no suspension prbs..
