Excellent
I added this as a secondary muffler or as a resonator to my already installed Borla system because it was way too loud and raspy.

I added this as a secondary muffler or as a resonator to my already installed Borla system because it was way too loud and raspy. The addition to this one fine tuned the exhaust note while toning the overall volume just enough. My exhaust sounds perfect now.
