So I know its been brought up 1000 times but I want an exhaust that's relatively close to stock sound when at idle and loud when I punch it .. I heard a GMPP and it was a sexy sound ! I'm just wondering if the ZZP matches close to that and if its possibly a little quieter at idle ? Not to mention I have a shorty header , and 2.5" downpipe I'll be putting in with the exhaust .. Thanks !
