2000turbosi

i wanted to make a skidplate for my 00 si, turbo, traction bars, and inlinepro downpipe...i was wondering if anybody has done this?....if so could you please give me some info as to where you got your materials and what exactly was done...im planning on just getting 1/4 steel plate and welding it onto my downpipe or traction bars....so if i hit anything it doesnt smash the dp....pics would help too....
thanks for any help
