Custom Performance Engineering (CP-e) is an American company that specializes in custom high quality parts
The cp-e™ MS3 downpipe replaces the choked factory pipe and its two restrictive cats and a 3″ mandrel bent pipe. The result of our efforts is reduced backpressure, decreased turbo spool time, increased horsepower and a more aggressive sound. For the greatest dose of great sound and power, option for the downpipe without a catalytic converter, though keep in mind that a cat free downpipe is for off-road use only.
Although more power and great sound are high priority items when buying a 3″ downpipe, the fine details are what ensure that the product will satisfy the end-user for a lifetime.
The cast bellmouth piece on the downpipe ensures smooth flow and transition. The downpipe includes three Oxygen Sensor bungs – two for the factory sensor and another to add an aftermarket wideband. Our Off-road version also includes the cp-e™ Tunable O2 Sensor kit to eliminate the unwanted check engine light.
The downpipe comes complete with all necessary hardware required for a complete and professional installation.
* A Tune and the purchase of an HPFP (High Pressure Fuel Pump) is strongly recommended with the purchase of this part. *
