Default Quiet -- stock like sound level -- turbo back exhaust

Hey guys. I have a 2016 sti, and am planning on installing a turbo back exhaust. Ideally I would install a catted DP and keep the cat back stock, as I'm happy with the sound.. But I don't want the restriction of the stock exhaust. I know it will be louder, but I want to keep the noise increase to a minimum, and definitely no drone on the hwy. Recommendations? TY.

I also wanted my car to have stock like sound, its my daily and my s2000 has a 70mm single and i need a break from that sometimes. I have the grimmspeed catted dp and hks legamax premium cat back. I would say it isn't any lounder than stock, you just hear more of the rumble. With the stock exhaust, i had some drone in the cabin during a cold start. That has been eliminated now. Eventually I will add an ELH, and from what I have read it should make it slightly quieter in the cabin.

You're not going to leave a lot of power on the table by keeping the stock catback. I use an SPT single catback with 450whp. People put melon-launchers on their cars because they like them or have a hard-on for Fast and Furious. That kind of flow really isn't needed until you're making a hell of a lot more power.

I have a catted DP. At one point a Perrin midpipe, now a Nameless Performance midpipe, both resonated. Finishing it off are stock mufflers.

It is slightly louder than stock. The 2 midpipes' sound and power are practically identical.

I also have NP 5" mufflers, but are a bit too loud so the stockers are staying. Stocker drone.

keep stock exhaust until you are going to get a turbo upgrade

Thanks guys. Here is some more info that may be relevant.

I'm going to run a Cobb ots stage 2 map for a while. I'm not sure that will be a good idea with the stock cat back. Will it work OK?

Then, I will be doing some fueling mods and a pro tune later on, possibly as soon as this summer. Will the stock cat back flow enough to get the most out of those?

If I will need to install one anyway I'd like to do it at the same time I do the DP. And, a little louder would be fine. I just don't want something obnoxious.

You're kidding, right? I had the same setup and that's total bullshit lol. Sound is subjective, yes, but this is false

Sorry wrong term, not close to stock, it's close to q300 catback only without the dp. But still, it's really quiet for me. I was thinking before to change to a different brand of catback only
