Default Downpipe smell (how bad is it)

Looking to get a catted downpipe (turboback) for my 15 wrx. I'm concerned about the smell, How bad is it? Is it a better idea to just upgrade starting from the midpipe with a catback to avoid the smell?

EDIT: Shoot wrong section, it was suppose to be in general. How did I end up here.

You need an AP if you add a J-pipe. What are your goals. Are you just looking for sound? or are you trying to add power?

Adding a jpipe and an AP will add power an a significant amount of sound where as adding a catback you do not need an AP and will also add varying amounts of sound on which one you are looking at

Your concern factor should be on whether you have engine management sorted to support going catless first and second whether you know about boost creep vs. catless and 2 weeks later....you can worry about the smell. Smell is annoying. Not knowing about engine management or boost creep can cause 4 holes in your fenders where the pistons leave the motor and exit through the fenders....put research into what's critical and not what is an opinion.

As Unabomber said, worry more about engine management and less about smell.
However, to answer your question, I just finished installing a full turboback exhaust on my 15' WRX, and only really smell anything after a pretty hard pull. It just smells a little rich. Personally, it doesn't bother me, I quite like the smell.
You're asking an opinion based question, what one person loves the smell of, you might hate.
