Bruce,
Turn downs arn't restrictive, they just need to be 3 1/2". You mentioned the pipes from the flange to the collector being 1 3/4". I think the previous owner cut the LS mufflers out and replaced them with something else. When you cut your existing mufflers apart, I think you'll find they have or have had something in them. A 4" hollow tube in a sidepipe would be unheard of and you can't tell by looking at them. All sidepipes are loud and will set off alarms, it's just a matter of what degree of loud. Just trying to help,
Tim
