Borla S-Type True Dual Cat-Back Exhaust System with 4.5-Inch Polished Tips (140449) - 2011-2026 Dodge Durango 3.6L V6 & 5.7L V8
Wake up the high-performance spirit of your SUV with the high-impact Borla S-Type Cat-Back Exhaust System. Custom-engineered for 2011 to 2026 Dodge Durango models, this premium full-length exhaust upgrade introduces Borla's legendary acoustic profile: the classic S-Type sound level. Formulated explicitly for driving enthusiasts and SUV purists who crave a highly aggressive, sport-tuned exhaust note under acceleration, this system is calibrated to give the 3.6L Pentastar V6 and 5.7L Hemi V8 engines a bold, crisp, and high-impact growl. This configuration delivers a commanding exterior acoustic presence while relying on advanced straight-through internals backed by Borla's official No-Drone Guarantee to keep the cabin completely comfortable and drone-free during highway cruising, daily commuting, or family road trips.
The internal engineering of the Borla 140449 targets key factory flow restrictions by incorporating an upgraded high-efficiency performance layout featuring a 2.5-inch diameter True Dual main pipe configuration throughout. This performance architecture integrates a dedicated precision-manufactured Merge X-Pipe that balances exhaust pulses between cylinder banks, maximizes exhaust velocity, and optimizes scavenging to unlock hidden horsepower, sharper throttle response, and enhanced fuel economy across the entire powerband. Designed to route flawlessly along the undercarriage, it safely clears models equipped with Rear Environmental Controls and leaves plenty of extra flow capacity for additional aftermarket performance modifications down the road. Built completely from premium-grade, aircraft-quality T-304 austenitic stainless steel, this highly durable cat-back assembly defends permanently against structural degradation, intense under-car heat cycling, and severe corrosion. The spent exhaust gases exit through a distinctive single split rear configuration featuring oversized 4.5-inch round, polished T-304 stainless steel tips on each muffler assembly. Precision CNC-manufactured for an accurate line-to-line bolt-on fitment, this system utilizes all factory mounting positions and is backed by Borla’s legendary lifetime Million-Mile Warranty.
Chassis & Configuration Notes: This true dual cat-back system is engineered specifically for the 2-Wheel Drive (2WD) and 4-Wheel Drive (4WD) automatic transmission configurations of the WD platform Dodge Durango equipped with either the 3.6L V6 or 5.7L V8 engine. It delivers an exact fitment for all standard trim levels including R/T and V6 models across 4-door SUV body styles. Please note that this system is uniquely engineered to clear vehicles with original rear climate management plumbing without modifying the original layout.
