My buddy has these on his 99GT and it sounds like no other mustang, and actually sounds more Camaro-ish. But I can't find a clip of them on an lt1 (or ls1 for that matter) for the life of me. Any help? The green one is his, it's easy to tell the sound.

Those sound like a beat up pickup truck sound.

 

sounds like ****, its gonna make your exhaust raspy as hell, which doesn't generally help the LT1 out
