Having said that, I think the CF ones sound awesome (there's probably little difference honestly). They have a slightly different sound, it's not quite as metallic or sharp especially when jumping up and down in revs. The LTH's and exhaust that my roommate had were crazy loud on startup but just had a slight burble at warm idle and while there was a lout of noise in the cabin from the exhaust, they didn't really drone much.
