Anyway, what I'm driving at is that even with a stock exhaust (if no secondary cats exist on it) will smell just as bad as an aftermarket exhaust with the AR CDP. There is no secondary filter (cat) to remove the smell... Hopefully someone can chime in though who has this or a similar setup to let us know.

it will smell with catless DP.
it'll throw a code (there's a fix for that)
if u have a sensitive nose, at idle you'll smell it. (windows up / ac on will shield it.)
driving u'll hardly notice -
like ernie said - u get use to it.
- xi n55 have 2ndary cats on mid pipe. primary cat on the DP.
- i n55 both cats are stuff'd on the DP.
u can get single catted DP if u don't want catless - that'll take
care of the smell.
