No sound bites, but I have TTI step headers, 3" X-pipe system and Dynomax UltraFlo mufflers ending at the rear axle. I like it much more than expected when I installed it over 2 years ago and have gotten lots of compliments from the open header racers. At idle I can hear my frame-mounted blue Holley pump, but it get pretty loud when I stomp on it. It flows pretty well because the 360 has gone 11.31 @ 115 weighing 3,540+ with unported 1.88" intake heads, .474" lift cam and 10.5 compression.
