I installed the TRD catback last night with the factory hangers. The new hangers showed up today 3 business days early(super fast)
Paired with a gruppe-s header and overpipe with the stock front pipe.
Stock hangers: At cruise the exhaust doesn't drone at all but under load and on deceleration I was getting some serious drone frequencies(for me). Especially in the 2500-3500 range. Deceleration was noticably worse. My ears are sensitive to pressure changes and were a bit sore when I got home from work.
I could see it in the rear view mirror shaking a noticably.
Tossed all five new hangers on. A intial observation; the catback has more left/right play. Maybe that will go away once the silicone lube dries up.
Then I went for a 20 minute drive. Noticeably less drone under load and on decel in the 2500-3500 range. The decel is still where it drones the worst. It didn't eliminate it entirely, but well worth $70. Enough to say I would be uninstalling this catback without the hangers. I may or may not keep it as I find it bordering too loud.
