Ya the sound like all the ones on the clip you attached. All those rumbles and popping are from headers and a tune not stock with just a catback.
When you listen to those clips keep in mind that many of those cars also have intakes and other mods as well as exhaust that change the sound. Try to find clips where they clearly state that the car is stock with just a cat back. Like I said though the clips can be deceiving.

Here's everything in a nutshell:

- want sound? Catback
- want more sound and some power? Header + tune. Tune is 100% required when getting a header or else car will trigger a check engine light. Getting the car tuned will void your warranty (if you have one) in most situations. Net gains from this vary but average around 20 whp.
- There are many options available, nothing below $600 is worth buying. Videos are useless because the sound quality always sucks.
- Loud exhausts (muffler-delete) will drone, always. Never combine a header and loud exhaust unless you want the attention.

Think about what sound characteristics you want your exhaust to have; that will really help narrow down the choices. Also consider equal length headers vs. unequal length ones (EL = more high end power and flat sound; UEL = burble sound aka "boxer rumble"). Don't rush into a purchase and do a TON of research.

Definitely, I want more sound rather than power, is enough for me what car has as I said before I will not run not as a pro not in a car competition just want my car sounds better than it does by default (stock options)

In this case and from your personal experience any recommendation for a catback?

Not sure I understood what this is but for now I'll keep away

Well that's the problem I would like my car to sound noising and powerful not that small sound that it have by default.

No ideas in what you're talking about or how this can help, again my ignorance

Looks like you got a lot of google searching to do my friend. I'll give you a bit more info but most of this is stuff you can easily find online.

- Equal length/Unequal length refers to the length ratio of the piping. Equal length headers have equal length pipes on each side, meaning that the exhaust gases flow at the same rate. Unequal length headers have one side of piping longer than the other, which causes the gases to go through the header at different rates which is what creates the rumble sound. If more power/low-end torque isn't a must for you then do not get a header.

- The muffler is the big chamber at the end of your exhaust. If you look under the rear of your car you will see it. Like the name suggests, it muffles the sound of your exhaust and eliminates drone. There are a lot of catbacks out there which do not have a muffler, i.e. straightpipe, and removing the muffler means that your exhaust will be significantly louder and will drone excessively. Drone means that no matter what rpm you drive at you will hear a constant loud noise coming from the exhaust. This can get very annoying in a daily driver and should be avoided.

- I am about to put this exhaust -> http://perrinperformance.com/i-23898...-s-brz-86.html onto my car. As you can see it has a muffler so it won't drone, and I asked other owners on here what the exhaust sounds like on their car and their descriptions matched what I was looking for sound-wise.

Well, the axle back I have on my 2013 is made by nameless performance and it has 2.5" piping and 2 - 5" mufflers.

I'm very happy with it ....... however, I understand it will NOT fit your 2017.

So, I would recommend an axle back OR for more of a selection. a cat back system.

Unless you want to drive yourself out of the car, I'd suggest you get a system with some sort of mufflers in it (not muffler delete).

Yep, I know what you're going through. I wanted a bit more sound but not so loud I couldn't carry on a conversation in the cockpit.

I just had to ....... PICK ONE .......

Well, if I had a 2017, I'd take a hard look at the one @Silver Cervy chose.

http://perrinperformance.com/i-23898...-s-brz-86.html

It looks to be well made and looks like it would produce a good sound without being too loud.

Ya, I know, almost $1,000 but it's a one time investment in your driving pleasure.....

Mine will be put on early next week with a JDL uel header. If you want @reynierpm I will post a video here so you can get a rough idea of what it sounds like (I know I said that videos are useless but they're better than nothing).

Invidia also just released their Gemini R400 which is similar to mine.

Yes. OP hasn't stated in black and white what he wants, so it'll be just another example for him to consider.

@N1rve just pulled a Perrin exhaust off his car (check the thread "what I did to my FR-S today") (post #15862).

Maybe he would sell it to you .....??

You might ask him how loud is too loud.

LOL I traded exhausts with someone in socal so I'll need to surrender the perrin.

But going back to the perrin, I had a 3 inch resonated. People said it sounded like the 2.5 unresonated without the rasp; it sounded great... between 4000-7000 RPM. Between 1000-2.5k it droned and made the car resonate with it (increased rattles). Since I don't drive my car like I stole it everytime, it sounded like ass (to me).

I could not have a conversation in the car with it as the drone from 1000-2.5k rpm was annoying and I was practically using my outside voice instead of my inside voice. I just installed the q300...it's practically the stock exhaust with rolled 4 inch tips. I wouldn't get the Q300 if you like loud exhausts or a significant volume change (change, not increase).

I thought it would be cool to have a loud exhaust, but I could not talk to people in the car, my coworkers would complain my car is too loud, and it would give me a headache sometimes. But that's just me.

I would highly visit a meet and listen to the exhaust hoe you would normally drive with load. Don't listen to YouTube videos or a parked reving car. You want real world scenario sound.

That's interesting. How would you compare the Perrin to, say, an N1? My impressions about the Perrin from all that I read was that it was louder than most exhausts but not excessively loud, and I never heard about any rasping for the 2.5" (which is what I bought).
