I bought this Roush exhaust system before finding out just how loud it is going to be. Can't fine any info on the D.B.'s with or without the factory resonator. My current is a Steeda X pipe with OEM mufflers with aftermarket tips and it produces 85 D.B's at 4500 RPM's ( the most the car will allow you to rev with a sustained RPM ) . Any help would be great before I jump in and install it.

 

I Did Post a Lot Of You Tube Vids on Exhaust. Might Glean Some Info Here!
