I was wondering if anyone had some db level measurements for the Greddy Ti-C comp cat back exhaust with an evo x and stock cat?

I was looking at the AMS Single, Invidia N1 and the Greddy Ti-c and there a few posts around saying the Greddy Ti-C is the quietest of the three.

I have Greddy Ti-C and I had AMS single before. Greddy Ti-C is much quieter than AMS for sure.

Thanks. I have tried out an AMS single copy and it was extremely loud. At 4,500 rpm I measured 110db on my android phone sound meter and my housemates bed would vibrate when I started it up in the morning =p
