You save: $325.05
The APR CBK0011 Exhaust is a satin finished T-304 stainless steel, CNC mandrel bent, cat-back system. The APR exhaust begins after the downpipe with dual 2.75" piping, and continues back through the center muffler and splits to quad 2.5" piping just before the rear valved mufflers and into the quad polished stainless steel slash cut 4" exhaust tips with the APR Tuned logo. The APR exhaust improves power and response and gives a deeper more aggressive sound. The valves on the rear muffler are controlled by the ECU to open or close as needed depending on vehicle operation.
The APR exhaust stands above the rest in several ways. The splitters from dual 2.75" to quad 2.5" are cast stainless to allow a super smooth transition with no flow disturbance. The valves are also enclosed in stainless housings and attach to the OEM actuators to retain functionality. The APR catback also includes a beautifully machined low profile center brace to increase ground clearance as well as improve chassis rigidity. The exhaust tips can be easily upgraded from the standard polished single wall stainless to change the style, size and finish of the tips if desired.
