15- Challenger 6.2/6.4L Axle Back Exhaust Kit

The 15-Challenger 6.2/6.4L Axle Back Exhaust Kit from Magnaflow Performance Exhaust is engineered for 2015–2022 Dodge Challenger owners running the legendary Gen III Hemi powerplants who demand authentic performance gains without full system complexity. An axle-back configuration targets the rear half of the exhaust system, replacing restrictive factory components downstream of the axle to unlock horsepower and deliver the aggressive sound that high-displacement muscle car drivers crave. This kit is ideal for enthusiasts seeking a bolt-on upgrade that improves flow, reduces backpressure, and transforms the driving experience on both street and strip.

Built from 100% stainless steel with polished 3.5-inch tips, this exhaust system combines durability with show-quality aesthetics that complement any Challenger's aggressive stance. The 3-inch diameter piping maintains optimal scavenging velocities while minimizing turbulence—critical for the high-flow characteristics of a 6.2L or 6.4L naturally aspirated Hemi engine. Magnaflow's Race Series construction utilizes mandrel-bent tubing and computer-optimized bends to ensure consistent diameter throughout, preventing dead zones where exhaust velocity drops and power is lost. The polished stainless tips resist corrosion and provide that signature Magnaflow finish that turns heads at car meets or cruise nights.

Installation is straightforward for any owner with basic mechanical aptitude or a shop equipped for exhaust work—no custom fabrication or welding required. The kit bolts directly to your factory intermediate pipes, making it compatible with stock catalytic converters and mid-pipes on all 2015–2022 Challenger models equipped with the 6.2L or 6.4L engine. Weighing 35 pounds and measuring 47 inches in length, it ships ready for installation with all necessary hardware included. Whether you're seeking a power bump for weekend cruising or building a corner-carving muscle car, this axle-back solution delivers measurable gains in airflow and that unmistakable Hemi rumble that separates true enthusiasts from the rest.
