I just bought a Greddy Evo2 and it sounds amazing but I just wanted to know that over the next few weeks if the exhaust tone might become a little bit more tame or come down a little bit?
my friend told me this and i was just wondering what you guys might think if this is true.

Thanks

it usually gets louder to my knowledge?

 

ohh really

BUMP for some more opinions

 

+1 to what Sergio07350Z said. Both my Nismo and HKS got louder after a week or so.

 

No.

 

my injen stayed the same......drones very loud inside cabin

 

I used to have a evo 2 on my rsx type-s and well it got louder after about 2months and deeper tone. Idk if its different on the z's though.
