AP Exhaust 78303 Exhaust Pipe

AP Exhaust 78303 Pre-Bent Exhaust Pipe

AP Exhaust 78303 is a pre-bent exhaust pipe built as an OE replacement for select Mazda CX-5 applications. It uses aluminized steel construction, a serrated bend type, and a welded-assembly replacement layout to match the original exhaust routing on covered vehicles.

The AP Exhaust Pre-Bent line focuses on direct-fit exhaust components for service replacement, and this part is shaped for the factory-style path used on the Mazda CX-5. Part number 78303 is specified with a 2.40 ID inlet, 2.36 OD outlet flange, and an integrated 3.5-inch round resonator with a 12-inch body.

Detailed Description

AP Exhaust 78303 is an exhaust pipe assembly for 2013-2021 Mazda CX-5 models listed in the fitment data. It is built from aluminized steel for service replacement use and follows the OE-style configuration needed for vehicles where the original exhaust system was a welded assembly. The pre-bent shape helps maintain the original exhaust path, while the serrated bend type and flange outlet support a factory-style connection point.

This part number 78303 is listed for 2013-2016 Mazda CX-5 and 2017-2021 Mazda CX-5. For 2017-2021 Mazda CX-5 applications, the notes specify that the OE system was a welded assembly and recommend replacing all parts noted [1].

What It Helps Address

• Damaged or rusted exhaust pipe sections
• Failed welded exhaust assemblies on Mazda CX-5 models
• Exhaust leaks at the pipe or flange connection
• Incorrect exhaust routing after prior repair work
• Noise from a worn or compromised resonator section

Installation Notes and Tips

• Compatible with 2013-2016 Mazda CX-5 and 2017-2021 Mazda CX-5, N/A position.
• 2017-2021 Mazda CX-5 notes indicate the OE system was a welded assembly; replacing all parts noted [1] is recommended.
• Verify inlet diameter, outlet flange dimensions, and overall length before installation.
• Check flange bolt hole size and exhaust alignment during fit-up.
• Because this is a pre-bent exhaust pipe, confirm the routing matches the original vehicle layout before final tightening.

Quality Assurance

AP Exhaust Pre-Bent parts are built for OE-style exhaust service replacement and application-specific fitment. Part number 78303 is engineered around the listed Mazda CX-5 configurations and uses aluminized steel construction for exhaust system repair work.
