i think the key here is "made overseas". how many turbo buicks do you think are driving around downtown China? a blue print is nice, its not so nice translated into mandarin and then shipped half the globe away. last time i purchased something from one of these 8000 plus feedback Ebay vendors with 97% positive, it was a camber kit for my last daily race car, a 92 civic hatchback with 240 Hp under the hood, 4 grand under the hood and 100 bucks on the only thing keeping me going straight down the road, when the front knuckle snapped on the freeway at 70mph, you can imagine quality was the biggest concern in my mind right next to not hitting the guard rail. i have pictures to show what an aluminum oil pan does against asphalt at 70. they might be cheap and a good deal, its really too soon to tell, but why gamble when the stock headers ALWAYS are a perfect fit, and are good down into the 10s? $240 to me ins't pocket change, id be pissed if i wasted it. as far as im concerned, any vendor online with a crap load of negative feedback selling car parts, isn't in the true spirit of things, its not hard to keep customers happy. now thats MY $.02
