I just got my dynatech headers only. Part # 715-14110. I took them to my exhaust shop ive used for years. He told me I need to get the flanges and crush ring for the connection pipes. Im goin true duals. On my 2010 silvarado 2x4 5.3. Does anybody know part #s for the flanges and crush rings or dimensions for them?
