My stock exhaust now that it has 30k miles is definitely louder now then before.It should be louder when it breaks in. I know my stillen got louder as it ages.
I had the nismo cat back on my 02 spec V and it got quieter as I put more miles on it....
Maybe you guys just got use to the droning on the highway and all that ruckus.It should be quieter when you get miles on. All the car that I had changed my exhaust, it took time to break in and then it got quieter.
