I said the question was vague because you didn't say what you were planning to do with the car. Anyways, it's not worth the money. The header is mild steel, the exhaust system is aluminized steel. The whole system won't last long, especially in Michigan. I'm not really sure about the performance gains. The exhaust system is baffled I believe, just like stock, but has larger diameter piping and I'm pretty sure it's mandrel bent, which is a plus. The header isn't really that good. The pacesetter header has been talked about in the 7MGE section.
