This is an effective and inexpensive way to tone down the Borla drone. The resonator added is a Trush 28" long, 2 1/2" pipe size. Its a smooth straight through perforated core. The cost is $18. from Summit. I also installed a Borla venturi sleeve at the end of the resonator outlet. The Borla tech I talked to said that the venturi is most effective installed as close a possible to the end or outlet of the muffler or resonator. The end result is very good. Its really quiet inside the car at all speeds. Outside is a bit quieter but still has the nice low note at idle.
