Exhaust fumes with test pipes

Are the secondary cats enough to get rid of the exhaust fumes if I delete my primary cats? Will a tune help?

I just checked out an E90 with xpipe and the fumes where too much for me.

There will still be fumes, but not nearly as much as if you ran catless.

it'll smell directly behind the car, but unnoticeable from inside even if the windows are down.

Unless you have an exhaust leak you will not notice it when you are in the car, if you walk behind you will smell it but its mild compaired to fully catless.
