The APR CBK0010 Exhaust is a satin finished T-304 stainless steel, CNC mandrel bent, cat-back system. The APR exhaust begins after the downpipes with dual 2.75" piping, and continues back and splits to quad 2.5" piping just before the rear valved mufflers. 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.

APR CBK0010 Cat Back Manufacturing:
APR exhausts are fully fabricated from T-304 stainless steel to prevent corrosion and ensure a long life. CNC mandrel bends are used to maximize flow and performance. TIG welding and CNC'ed hangers ensure a perfect fit. Ultra-smooth cast stainless 2.75" to quad 2.5" splitters ensures no restriction in the transition to the dual mufflers.
