On the N54's people said during cold mornings the car would idle erratically with DP's because the ecu wasn't seeing what it wanted to see from the O2 sensors.

smell is an annoyance, specially if you park underground or covered lots. Cold starts are ok, slightly louder for a minute or so. Idle is not erratic at all.

Its a worthwhile mod and for the N55, one of the better mods to add power - I say go for it. I think AR has an F10 downpipe or the dr euro.
