I just installed the Borla ATAK yesterday.
Why is everyone saying the thing is crazy loud or sounds like a Honda Accord? Based on all those reviews here, I was almost scared of putting it on, but in hindsight it is a) not too loud at all (it's just right, literally) and b) doesn't drone at any point and c) does sound like a V6 race exhaust, and not like a cutoff Honda, even at full throttle. I was surprised at the "deep rumble" at low RPMs that's more akin to a V8. With regards to those 3 points:
a) Be embarrassed in front of the neighbors? I'd be surprised if they even notice the exhaust changed. If one is embarrassed of how they look or sound in front of their neighbors, maybe the actual Honda Accord would be better for them.
b) Make sure stuff is properly bolted down and adjusted. There is almost no cabin noise difference to the stock exhaust for me.
c) "Sound like heaven" - I can only say that's true. It sounds f****** amazing. Couldn't be happier. Rumble, versatility and no "dying-cat" like tin-raspy sounds. I'm almost tempted to say now that my exhaust must be a higher quality production grade than others, but that's very unlikely. It is clearly a Borla ATAK, not S-type or anything else. Resonators are gone. Wouldn't want them back either.
I just think that some aftermarket exhausts do improve the sound of the Raptor. Maybe the reason why many think it sounds like a can of bees is because they’re so used to the American muscle car sounds. If you had this exhaust on a RS5, RS7 or M4, everyone would say “wow”. It makes a great TT V6 sound. Sure, stock sounds pretty great and if you’re not bothered with the volume level, then no need to spend the money. I’m very happy I did. Also got a good deal on it anyway!
With regards to performance: I honestly can’t feel a difference at all - but that wasn’t my goal either.
