Hey guys. Just wanna start off my saying that I have searched lol :-P. And here's my thing.
I got my topspeed exhaust not that long ago and when I first got it it seemed nice and loud. Now I feel like it has quieted down a bit. I understand that there is a break in period for exhaust systems but this exhausted wasn't new so I assume it has already been broken it..
Maybe someone could shed some light on this. Thanks guys. :-D

 

Thats how it was when I got my nismo used too. It was loud and seem to be more harsh but after a while it quit done and was a lot more smoother like all the other nismos. So its normal.

 

You probably just got used to the sound.

 

That might be it. I like the loudness. Lol
