I actually had test pipes before these, and went to them because I hated the smell and hiss. If anything, the slight increase in back pressure gave more mid range TQ, still gave me plenty of top end, the sound was still nice a loud (with my ARK exhaust), but more refined, with MUCH less hiss, and no smell.
As for CELs, I never had one, but I was tuned, so Im not sure if that matters. They have a decent length downstream O2 port, so that helps reduce them Im sure.
