The cp-e™ MS3 downpipe replaces the choked factory pipe and its two restrictive cats with one high-flow cat and a 3? mandrel bent pipe. The catalytic converter features a high-flow, all metallic honeycomb design, making it one of the most durable converters on the market. 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, is made in the U.S.A, and includes a full lifetime warranty.
