I got to hear a Cobb and I was not all that impressed although I will say that my thought of who would buy it was 40 something + people. I am in my 20s and thought it was not much louder than stock for the price. It sounds a little deeper but honestly I rode in another car and in an enclosed spaced I couldn't hear the exhaust even though the car was in front of me. I could hear the blow off but not the exhaust. It is that quiet and in car is roughly the same. If you can I recommend trying to find someone with one even if you have to drive. It looks great and I am jealous of the tips for sure, but seems like a lot of money for a deeper toned stock exhaust. Also I don't know about the muffler but I took out my resonator and it is straight through so getting better flow by removing that will be difficult. I got pretty close to the same sound as the cobb for $40 by removing the resonator. I can confirm it is very quiet even with a catless dp. In car I can hardly hear anything at low speeds and once over about 40 mph tire and wind noise overwhelm the exhaust note so drone is not a problem.
From what I have seen and heard it seems like you can have one of 2 things with our cars. A exhaust that does not drone but also does not fill that want for a strong in car exhaust note. Or a great sounding exhaust that makes driving fun until you get on the interstate and have to deal with the drone. There seems to be no middle ground. I really like the CP-e but have seen where people complain about it being too quiet also. There may be no way to have it all with our cars. Although cut outs seem more and more appealing lol

To the OP, note there are an increasing number of posts in various threads of people regretting their exhaust decision, or the decision to simply hack up the stock. They talk about their regrets due to drone and being too loud and reference "very expensive mistake". It's hard when choosing an exhaust, because the only real way to choose is to hear them in person. Listening to youtube clips is useless. I have made more exhaust mistakes than I care to admit, the worst of them being a small 4 banger turbo (Neon SRT4). The drone on that car was way worse than anything else I had done, mostly V8's.
And my best exhaust decisions have been high quality aftermarket products, the Corsa being my all time favorite. Corsa for the V8's is very similar to Cobb's approach. Pretty quiet at cruise with no drone, but a much better sound when you're in it.
Lastly, I wouldn't go with the age thing. If you've spent some time at the drag strip, most of the fast guys (not Fiesta fast, but say, 9's or better) are guys in their forties. And their cars make a straight pipe Fiesta sound like a pin dropping.
