Interesting this. I am a quite sensitive person when it comes to bad smells and so, and most of the time, especially if I am not going too fast I always drive with window down, no a/c, after the install of N55 mids which are catless and Evolve Race rear exhaust I have sensed zero change vs stock, absolutely nothing. I agree that it is a pair of cats less so there should be some change but there actually is nothing to talk about, whatever it is it must be too small a difference.
Or the resonator of the N55 mids has a hidden function!
Or your downpipe got weaker because of the badass Akra mids?
