Description
aFe Axle-Back Exhaust – 2022–2024 Kia Forte GT 1.6L replace a factory exhaust section with a freer-flowing, mandrel-routed system that also changes the vehicle's sound and rear-end presentation. This listing is built around aFe POWER part numbers 49-37039-P, 49-37039-B, 49-37039-L, 49-37039-C for the 2022–2024 Kia Forte GT 1.6L.
aFe's performance exhaust systems are engineered around tubing diameter, bend quality, merge transitions, muffler/resonator strategy, hanger placement and tip configuration. Those details determine not only restriction but also tone, volume, clearance and how well the system integrates with the chassis.
What This Means on the Car
An exhaust should be selected for the complete use case. Larger tubing and lower restriction can support additional airflow, but sound character is equally important on a street car. Axle-back systems primarily change the rear section and sound; cat-back and larger upstream systems address more of the exhaust path.
Verified aFe Technical Details
aFe's installation documentation confirms this 2022–2024 Kia Forte GT 1.6T axle-back family and identifies the available Black, Polished, Carbon and Blue Flame tip configurations. The system installs from the first factory flanged joint, uses the supplied gasket/fasteners, a 3-inch band clamp at the Y-pipe section, factory rubber isolation mounts and clamp-on rear tips. aFe recommends re-tightening the clamps and hardware after approximately 50–100 miles.
Configuration Guide
Tip Finish: Polished, Black, Blue Flame, Carbon Fiber. This selection changes the specified finish/appearance; choose the option that matches the rest of the build.
Fitment & Part Numbers
Application: 2022–2024 Kia Forte GT 1.6L
aFe POWER part numbers: 49-37039-P, 49-37039-B, 49-37039-L, 49-37039-C
Fitment can differ by engine, drivetrain, trim, factory equipment, emissions configuration and production date. Match the part number above to the vehicle before installation; where aFe publishes SKU-specific installation or emissions requirements, those requirements take precedence.
Legacy Racing Enthusiast Perspective
We recommend deciding first how much additional sound you actually want, then choosing the system architecture. For track-capable street cars, we also consider local sound limits and whether a muffler/resonator configuration leaves enough margin for future engine modifications. On the 2022–2024 Kia Forte GT 1.6L, we would make the purchase decision around the limitation this component addresses and how it fits with the car's current and planned modifications.
