lol... Not saying it doesn't sound good. Just a little too much for me. In my younger years I was All about the loud, obnoxious and aggressive exhaust note. Now I like an equal balance of not too loud yet not too quiet.

Like I said before, in sport and sport+ you can make the car be loud especially choosing what RPM range to drive in. In comfort and auto mode the car sounds nice and refined and does not pop much, and in eco mode the car is pretty silent. It's nice to have the options of how loud I want the car to be at literally the press of a button.

personally I want to have the louder exhaust because I think any exhaust system will be quiet in eco mode so like you mention at a press of a button you can choose the sound you would like but if you have exhaust that's already kind of quiet then there's not much excitement in sports mode either way.
you think the borla would sound louder than the agency power both would be catback?

Yea I think the Agency Power is quieter. The Borla catback doesnt have a resonator I dont think. I got lucky and found someone selling only the Borla atak muffler so im running that with just a catless downpipe so the stock resonator eliminates the drone and the car can be extremely loud when I want. If you do the agency power I'd do the downpipe. If you arent planning on ever removing the downpipe stock and going catless then id get the borla

alright I've been back and forth with this damn it to exhaust systems for a whole week but I think you are right it does seem louder in the videos but would you say it sound like a muscle car or a European sports car that's my only concern with the borla since they're so popular with American Muscle and I don't want my car to sound like that?

well there's Toyotas that can sound like a muscle car lol so there's definitely exhaust systems out there that will make your car sound like what you wanted to be rice rocket muscle car whatever I want mines to sound like a proper European sports car.
Borla does have that warranty and established name brand I'm pulling back towards borla again lol

I'm not knocking or dissing at all, cause it's not a bad thing but I personally think the Borla gives the car an American V8 Muscle sound as opposed to the Agency which gives the car it's rightful European Sports Car sound. The #1 reason I went with the Agency exhaust was for the authentic European Sports Car sound. I've read quite a few threads of Borla owners being asked what size V8 they have on other forums!?.. And I've been on and read a lot of threads in different forums. I find Bimmerpost to be the most informative, and most of all the "Most Friendly", so this is the forum I stick to now. You're not going to go wrong with any exhaust you choose. Search the sound clips and let your ears decide. That's what I did and couldn't be happier. Any opinion you ask for is going to be partial to that person's liking and what they baught. Same goes with most all mods. Any FMIC, DP or CP is going to be better than stock or none at all. It's just a matter of what kind of a budget you're on. Some are on one and some aren't.

Ok, I give up....lol... Not saying our Bimmers sound Anything like any car in particular. Especially a Mustang. Those things are very unique to themselves in their exhaust note, kinda like a Harley. You know when ones going buy. Just saying, MY OPINION is that the Borla has a deeper more thunderous sound like an American V8.

You certainly can't go wrong with a Borla system. Very reputable company and I'm sure the fitment is spot on. Unlike my Agency which had to be tweaked by a custom shop. I still love it though and glad I went with it.
