does this apply to the AT 2017s?

Ok, So I guess what I actually want is a catback. I don't know why but when I first thought catback I included the frontpipe, but that has a cat in it that I want to keep.

Look deeper there is a couple that state 2017MT. Get those. Do not beleive anything associated with the intake and exhaust will fit if it states 2013+.

Is there really a point to getting a Catback over an Axleback for the MY17's though. From me looking around because I too am interested in getting a new exhaust, it seems like changing a lot of the exhaust is a waste of money unless you're going FI, which you would then need to change all the way up to the headers.

My main issue is I want the car to remain legal lol, but want a bit more of a snarl for a price that isn't wasted money, but exhaust shopping is so damn hard for a noob and Axleback pricing compared to Catback is all over the place

It's all just for noise really.

Exhaust shopping too hard.

I'd just start with a header. Keeping it legal could be an issue. You'll get a check engine light unless you get a ecutek tune or an OFT tune.

But getting a header seems wasteful considering the MY17 updates, no?

No, there are still improvements to be had. I have a JDL UEL header and an OFT stage 2+ tune and it's definitely an improvement. Almost no torque dip, and even with the rest of the exhaust stock you get a nice tame rumble to the exhaust note.

Per dollar is that actually worth it though, considering my personal main goal is sound first. I would need to buy a header/tune which ends up being a lot more than either a Catback or Axleback.

Would this also not create a bottle neck? because you're opening up an area that is getting the exhaust first, but the remainder of the system is unchanged, which would be expecting stock levels of exhaust flow??

Not really.
Pretty much all catbacks are just for noise.

Not like it makes a huge difference, but I'm pretty sure the MY17 tips are the same as the MY15 and MY16 tips.

This is making me think that changing your exhaust at any point is a poor decision..

There are many perfectly valid reasons to change the exhaust. Most depends on your goal though. If you just want noise and simple cat or axleback is plenty. If you want performance than you need to open it up with a header and eliminate the cats. The actual muffler (even stock) will not be your bottle neck. Once you start messing with the whole system you can get some noises that may not be what you expect though. There is zero point in changing any of the exhaust without doing something with the intake and tuning the car for the change. Sure you can get more exhaust out but where is the advantage if you are not bringing more air in or changing the tune to be able to make use of that freer flow?
