Description

Route exhaust gases from the engine into the rest of the exhaust system with the Walker Exhaust Y Pipe 70402, a pre-bent pipe that drops in as a direct-fit replacement for the 2007-2015 Mazda CX-9. This Y pipe merges and carries flow downstream, and its precision bends are made to line up with the factory routing for a straightforward installation.

Aluminized steel construction: built from 100% aluminized steel for durability and corrosion resistance.
Fixture-checked fit: formed on precision benders and fixture checked so it seats correctly for quick, easy installation.
Connection sizing: 2.25" inlet (I.D.) to 2" outlet (O.D.).
OE-style design: hangers, routings and connectors follow the original layout where applicable, and it is designed to perform and fit like original equipment.

For a complete exhaust refresh, pair this pipe with Walker catalytic converters, mufflers and accessories. Signs an exhaust pipe may need replacing include a rattling or hissing exhaust leak, louder-than-normal exhaust noise, or visible rust and cracks along the tube. See the Buyer's Guide tab to confirm the engine and application for your vehicle.
