Product Description

The Borla 140436 is an ATAK cat-back exhaust system engineered specifically for the 2011-2014 Dodge Challenger SRT-8 "392" with the 6.4L HEMI V8, covering both automatic and manual transmission configurations in RWD 2-door coupe form. Built from premium T-304 austenitic stainless steel with CNC-precision manufacturing and ultra-smooth mandrel bends, this system replaces the factory exhaust from the catalytic converters back as a direct bolt-on assembly requiring no cutting, drilling, or modifications. The included merge X-pipe connects the dual ATAK mufflers and sharpens the exhaust note -- delivering Borla's most aggressive street sound profile with no interior drone at cruising speed.

Borla's patented straight-through multi-core muffler technology reduces restriction and increases exhaust gas velocity simultaneously, translating to estimated gains of 7-10% in horsepower and torque while improving throttle response. The quad square polished T-304 stainless steel tips -- slant cut with rolled edges -- finish the system with a purposeful, track-inspired appearance. As a 50-state legal system, the 140436 is street legal in all 50 states including California. Proudly made in the USA and backed by Borla's Million-Mile Warranty.
