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.
A fourth O2 bung option is available. This option is also useful for those who are looking to run a stock-frame turbo with an external wastegate on our LTRmani™ Turbo Manifold. IF you already have our downpipe and are interested in this additional bung, contact us at [email protected] or (301) 576-6142.
While this may not trip a Check Engine Light, we cannot guarantee that all of the codes will be in the “ready” state.
Mazdaspeed Turbo Downpipe Highlights
With the stock turbo design of the Mazdaspeed3 Turbo, the only way to offer perfect fitment is with a cast bellmouth on the downpipe. The non standard flange design doesn’t allow for any other solution, and we made sure to optimize flow on our new version. We also added in additional O2 bungs for our customers that want to run a wide band sensor.
Optional High Flow Cat
The cp-e™ Mazdaspeed3 Turbo Downpipe is available with or without a high flow catalytic converter. Maximum gains can be found without a cat, but the catted version is incredibly high flowing and sees extremely low parasitic loss from the catalytic converter.
