aFe's Takeda axle-back system is aimed at easing the restriction of the factory rear exhaust on the 2024-2025 Mazda CX-90. The mandrel-bent 304 stainless steel tubing steps from 3 inches down to 2-1/2 inches, and the hi-tuck tip is designed to add clearance on steep approaches and departures. The manufacturer's dyno chart lists gains of up to 19 HP and 32 lb-ft, and the stainless build resists the rust that shortens the life of cheaper mild-steel pipes. Buyers who would otherwise pay for custom fabrication also avoid cutting and welding, since the system bolts directly to the factory setup with no cutting or modifications.
The manufacturer's application list names the 2.5L four-cylinder hybrid and the 3.3L turbocharged six-cylinder, so check your engine before ordering. For the install, the kit includes a muffler assembly, driver and passenger tail pipes, V-band clamps, flange hardware, and a gasket. Enthusiasts searching for a CX-90 axle-back exhaust, a 304 stainless CX-90 muffler upgrade, or a bolt-on rear exhaust for the 2.5 hybrid and 3.3 turbo will find the key details here.
The manufacturer lists the 2.5L L4 hybrid and the 3.3L turbocharged L6 for this system. Its installation sheet is written for 2024 and later CX-90 models. Confirm model-year coverage with the manufacturer before ordering, because its listings show different year ranges.
No. The manufacturer states that the system uses factory-style flanges and hangers and requires no cutting or modifications to bolt on.
Per the manufacturer's installation sheet, the kit includes the muffler assembly, both tail pipes, two 2-1/2 inch band clamps, two M10 flange screws and nuts, and a gasket.
The manufacturer describes this as a bolt-on job that reuses the factory mounting points. Per the manufacturer's install sheet, you should coat the V-band clamps with anti-seize and hand tighten them to 10-15 ft-lb. Leave the clamps and flange fasteners loose while you align the system, then start tightening from the front of the exhaust and work rearward so every component stays at safe clearance from the body and driveline. Confirm the tip and hanger alignment before final torque. Owners on user forums have not been quoted here for install difficulty, so plan for a standard driveway job with a torque wrench.
