Have yall seen this video of Headers/exhaust transforming the sound of the LS3?
We have 3-1 headers equal length hooked up to a Y pipe style exhaust that changes the sounds dramatically on an NSX:
But what about the resonators that cancel low frequencies?
That's fn-09 y pipe with headers as an example. Still some low frequency baritone in there that could be cancelled out perhaps with the resonator packing as mentioned in the celeritech mufflers at 4:33 for LS3 Video?
