Sorry I hven't been back on this thread in a while. I have ran numerous header options on 20r and 22r engines. I ran the dougy and lce both on the same engine in the the same truck. Could be that it was not a stock truck on 29" tires, but I felt zero difference between the two. Either is an upgrade over factory cracked manifold. Both would be an excellent choice in my opinion.
I re-read your post. Are you saying that you could NOT tell any difference between the LCE and DT, or that you could not tell any difference between the LCE & DT and the stock exhaust manifold?
