I just ordered some Heddman Tork-Step headers for My 87 trans Am with the 305. I also ordered the American Thunder Flow Masters as my cat back. When I was askign the guy from summit about getting a Y pipe to go wiht the headers, he told me that my stock one would work. After many hours this was found to not be true. So my headers which are not ment for street use are not at all connecting to the Y pipe. I need to have one custom made or something, because I do not want to get different headers. Help anyone if you can. Ideas are appreciated.
