2nd Gen Non-Engine/Transmission Hunting for that turbo "whistle"

[LOtero]

my truck is about as loud as a stock turbo'd truck can get, straight 4" with a scotty II with a hole in the cowl and no silencer ring, i love the sound, and it also makes for a great girlfriend filter. . if she doesnt like it... . bye bye!! its also fun to bark the turbo when people are in your truck and see the look it puts on their faces! great thing about doing the scotty with hole thing is that you can always cover the hole up with the insulation inside the hood if it gets too loud or whatever... i still havent found a reason. .
