I made sure I did that on the O2 housing and where it connects to the cat-back. Still too close for my comfort. I can push it with my hands and it will touch. I was also thinking about some Kartboy hangers to minimize the movement some.
Also after installing the e-bay o2 I no longer needed the washers on the tie bars. My downpipe was about the width of a nickel away from my TC.
I think this has been discussed many times before.. if you have an 05+ EVO w/ ACD and front LSD, any 3" downpipe will give you clearance issues. Stick w/ 2.75" and you will be ok. you won't notice any difference between 2.75" and 3" downppe in terms of power gain unless you are way over 600hp.
If you use just one of the two front kartboy hangers it´ll pull the DP away from where it hits. That is, you leave one compliant, stock hanger and put the tighter kartboy unit on the opposite side, so it pulls the DP away from where it´s hitting. Also you can bend one of the two hanger rods on the DP away so that it pulls the centerline of the DP away from the side where it makes contact. I did these two things and there is no more interference.
