Very loud under light and medium throttle. I'd venture to say it's at least 80%louder than stock under these conditions. At WOT, it's only maybe 20% louder. I had the Borla for about 5 days, but the noise was concern seeing that my son rides in the back where the drone was almost deafening. The guy that bought my exhaust gained about 5whp.

Is the Borla Exhaust louder than the Stillen Exhaust?

What Borla did you get?!?
I added this the first week I had my car. At the time my only engine mods were a stillen intake, utr cf z-tube and 5/16 spacer. It was not that loud at all. Under normal driving it was maybe 20% louder at the most and sounded awesome! On hard driving it is a little louder but still not loud at all.

Borla vs Whomever.............!
Since I'm on my third exhaust system I gotta tell you I was never impressed
with how the Borla system a. sounded b. looked c. fit and finish we're not
as good as many others! Check out www.utube.com and listen to what's
available.....Stillen systems for sound, fit and finish are second to none!
But check out utube and search for what sounds good to you. There's also
sound clips on www.magnaflow.com.....LOL

Another thing that bugged me about the system was the lack of flex sections in the y-pipe. I really don't know what these companies are thinking by not putting the flex sections in the y-pipe. The purpose of the flex sections is to reduce noise/vibration/harshness (NVH). The Borla caused an annoying slight vibration in the cabin that was inline with the drone thanks to the lack of flex sections.
I'd never recommend a TD exhaust for these cars if the person is concerned at all about noise or NVH. The gains really aren't there either for the compromises. 4 to 7whp (Dynojet) is about the best you can hope for.

I got the coupe mid on right now and I love he way it sounds on the outside but its a little to loud for me in the 2300 to 3300 rpm range. There is drone and it seems as if it is worse than the straight pipe was. That does not make sense to me. Stupid question, are you supposed to remove the metal shield the is between the drive shaft and the resonator? It seems to me as it it hits it when I go over bumps.

As for the shield, yes, you need to push the shield up a little to give the coupe midpipe a little clearance. I just did it with my hand.
