Lexus ISF 5.0 V8 launch / flybys / downshifts / WOT / loud / 2.5" x pipe straight pipes (4k video)

part 2 https://youtu.be/sd_MdgxWbps

Launch WOT from a dig w/ 2.5” straight pipes no mufflers.

Lexus ISF 5.0 V8 fly bys and take off

At time of video stock headers w/ cats to 2.5” piping xforce catback w/ mufflers deleted only. Personally would not recommend. Whole interior and occupant teeth rattles/chattering without even having stiffer motor mounts or upgraded headers at this time
Note: Can anyone tell me what that "chirp" sound is from the front??? Is it a belt? Only happens at WOT/High throttle application.

part 2 https://youtu.be/sd_MdgxWbps - little more tame even though de cat and headers due to added muffler and helmholtz tubes.
