Agency power is proud to release its super sport exhaust system for the 958 Porsche Cayenne s v8 2011 and up. the super sport exhaust is a axle system that gives your 4.8l v8 engine a real aggressive tone. made here in the usa, the exhaust saves close to 30lbs off the rear end of the vehicle. using 304 stainless steel and detail oriented tig welding, the exhaust system uses two small high flow mufflers which give it the sports car rumble. its reduced back pressure design gives the engine improved horsepower and torque with most noticeable improvement in throttle response. because of the reduced restriction, this exhaust horsepower gains can definitely be noticed in the mid to top rpm range.

Even though it has a loud rumble under acceleration, the super sport exhaust has a low drone sound inside the cabin under general cruising. since this is a luxury suv, we wanted to ensure business could still be conducted for everyday use. to test this, we made several phone calls using the factory bluetooth system to see how the exhaust might affect communication during highway cruising. Crystal clear sound! the exhaust is designed to work with OEM tips or OEM replacement tips that are available. as pictured, it utilizes the stock hanger positions for a secure and safe mounting. it does require cutting the OEM muffler off as shown in the installation pictures. the axle back exhaust is then connected with the supplied clamps (not shown) that go over the agency power side and OEM side. you also have the option to directly weld the pieces together. since this is a axle back unit, this retains all factory catalytic converters and will not cause any check engine lights. this exhaust will fit the 2011 and up 958 chassis Porsche Cayenne s v8 only.
