Any exhaust clips of 63 w/ no cats and different exhausts?
Any video with no cats or resonator (or pictures of what's inside the resonator) would be helpful.
FWIW, I'm looking at adding two high flow mufflers and an X pipe right before the rear axle.
I have attached clips of cold start and getting on it from inside the cabin.
fyi, every valved exhaust I looked into is louder with the valves closed than stock.
I think high flow cats with stock exhaust is what I’d do if I had it to do again.
