None on my '02. I think that is the diff between Michigan and Colorado. Was in Detroit last week and all the blacktop roads were white! However, I think this could cause serious problems down the line and best to repace those rusty pieces with some Stainless Steel long tubes!!
I'm already conditioning my wife's mind - 'told her I might need to replace the headers soon, otherwise it (rust) might spread out and cause more problems. I gotta take it slowly though because i just spent some money on Caravaggio seats.
