Shoot, I just placed an order for 5 CUSCO exhaust hangers! I realize the Nvidia N1 itself causes a lot of drone and these hangers may not fix it (or by much). I don't want to get rid of the Nvidia because I just bought this car 15 days ago, and the reason I bought it was for all the mods (headers, OFT, coilovers, exhaust, CAI) at pretty much the same price of a non-modded car. So I don't want to start replacing mods, I'd rather use any money to by other/new mods. Plus, there is one bonus of at least some drone: my 2 teenagers may THINK they are going faster than they are, and not speed.
So to reduce drone, I will be taking a multi-faceted approach and try these hangers first, and if not try to get a J-Pipe custom made, and/or save up and buy a dual resonated FP or FP with Helmholtz - all that is on the table. Even stuffing the trunk by the spare tire with blankets or sound-muffling pads could be an option (as I saw in another post).
However, I have read and re-read this thread many times and I thought that the reason the cabin noise / drone was reduced for the original poster is because the stock FRS/BRZ has too much slop / play / movement in the hangers? The STI part number hangs them more securely (or so I thought), reducing vibration into the chassis? If so, then the CUSCO part which I think is polybronze should hold them even more firmly? I thought the person who posted them above said he had success with the CUSCO's, no ?
