Hedman headers opinion
I just bought a set of headman headers and matching y pipe for my GTA. They are part number 68470 amd the Y pipe is 17470. I will have to have an O2 bung welded on to one of them, but no big deal as I picked them for $100.
What is the opinion on these from those with experience?
