This exhaust does not drone.. Loud maybe yes with the header/front pipe combo, but even then there was no drone.
The greddy evo3 I had droned HORRIBLY with just the catback. Maybe you mean it's just loud, or maybe not having that cat in the front pipe really makes that much of a difference. But when I had the header on there I was down one cat and there was no drone.

My other vehicle is a 400whp GTO, that, for a time I ran straight dumps on, right off the header.
I know the difference between loud and drone
When accelerating under heavy load the car drones; pressing the accelerator down in 6th gear in the dreaded torque dip between 2000-2500rpm. It just does. At least -- again, I stress -- with a test pipe. I've never known an aftermarket exhaust that didn't to some extent and, as I said, this is definitely one of the best I've experienced, and that's with a catless pipe even. I don't doubt that with just the catback, it's not an issue at all. And, besides, it's a good excuse to downshift as the increase in revs drops the drone to almost nil.
I will say that after some break-in time this has improved considerably. And it's not me 'getting used to it' either; as I only drive the FRS once or twice a week. It has genuinely improved by a fair margin. I will still do something to cut down the sound in the cabin, but that was always the plan anyways due to road noise and should take care of the last of the remnants.
To reiterate my original post -- the sound of this exhaust setup is absolutely epic. Even if it did drone badly I would put up with it because it just sounds that good. The fact that it really is minor is just that much of a bonus. I'm currently planning a 4000-mile road trip; if the drone was bad, I'd never consider it. But, to put it in perspective, I won't do it until I cut down the road noise -- so,
to me, the road noise is worse than the drone I'm experiencing. So if you're not bothered by the road noise present in a stock vehicle, you surely won't be bothered by the drone; and even less so after it breaks in a bit.
