I have an 01.5 High Output CTD in my truck and a guy I work with has an 01 Standard Output CTD in his truck. Side by side at idle with the hoods up my truck is much much louder than his. And by louder I'm talking rattle from under the hood, not exhaust note. It sounds like my VP44 makes a lot more racket than his does. It doesn't sound "bad", it's the same sound as my buddies standard output just a lot louder. Has anyone else experienced this?
