Here's a couple clips I shot of my resonator delete with the VelocityAP tune installed. I tried to capture the gargles it makes at low RPMs but the crackles and pops are harder to film from a stationary position. Perhaps a GoPro mounted on the rear bumper would do the trick. Note that I did have an X pipe installed post-resonator delete so this isn't a true straight pipe. I would recommend headphones & 1080p, it sounds pretty true to life for me. Let me know if you guys have any questions.
