Help with Downpipe

[lock5]

Hey guys I'm new to all of this, and my car is stock as of now..

I bought an aftermarket downpipe with intentions of a better sound...
I'm just wondering what's best to pair with that, (css, resonator,etc) or if i even need to add something else for now??

Also getting a tune in a couple of weeks so i know that will help, just asking if downpipe is enough

thank yall! any advice helps

I would just put on the downpipe for now, and see how you like it with the stock cat back. Can always change more exhaust components later.
