Borla Performance Cat-Back System Audi RS4

The deep throaty sound of performance that comes from this Borla Cat-back system is just the right touch for the RS4 (7.4 db�s over stock). The system is made of 2.5 inch austenitic, stainless steel, pipe and straight through mufflers that add 84cfm�s of flow over the factory system at the same time weighing in 48 lbs. less.
