I was planning on buying Skunk2 Alpha Headers for my type s and I saw the price on the skunk2 website and saw that it was 470$. I decided to check up on eBay just to see if I'd see anything. I found this poster with great reviews and it seems like a lot of people buy from this specific eBay poster. What do you guys think? The headers is 70$. There's warranty with it as well as returns. Would this be a smart purchase?
