Well all 2005-2006 designed downpipes are made to clear the ACD. Sometimes hangers can wear and the DP will rattle against the transfer case. From what I have read, all the DPs are good at clearing the ACD except for the ebay version.

thanks for the input, I have been using a 2.75" DP since '06 when some of them would hit theACD and some actually overheated the ACD. I guess most of the manufacturers have corrected this problem. If I change to a 3" DP will there be any additional gain if I change the O2 housing as well?
