I wouldn't mess with UDPs....especially on the dtec. Too much hassle to put them in for the little bit of gain, if any. I assume that you know about the crank pulley bolt on the dtecs? That it releases tension off the timing chain when you take it out and can damage your motor if not properly put back together.

On the exhaust stuff....it should be fine. Its only a 1/4 of an inch on each side. The flanges should have slots in them to move the bolts around to get them to seal right.
