Video is uploading to YouTube as we speak. Will post in a few minutes.
US spec (no OPF sensors or secondary cats) Stock downpipes, stock muffler with flapper valves welded open permanently.
Resonator deleted. Custom 3" double H-pipe installed, with cross sections 12" apart from one another. Cold start.
Happy with tone.. very rumbly and low
Happy with the lack of crackles and pops (I don't care for that)
Not as happy with "volume". I expected more. Barely noticeable inside the car. Zero drone whatsoever.
Noticeable 800-2000 rpms.... and at full acceleration. Otherwise, no difference in volume from stock.
