Borla S-Type Cat-Back Exhaust System with Single Black Chrome Tips (140791BC) - 2018-2024 Dodge Durango SRT 6.4L V8
Wake up the high-performance spirit of your SUV with the high-impact Borla S-Type Cat-Back Exhaust System. Custom-engineered for 2018 to 2024 Dodge Durango SRT 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 performance purists who crave an aggressive, sport-tuned exhaust note under acceleration, this system is calibrated to give the high-output 392 HEMI engine 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 driving, or family road trips.
The internal engineering of the Borla 140791BC targets key factory flow restrictions by incorporating an upgraded high-efficiency performance layout featuring a 2.75-inch pipe diameter that routes perfectly under the Durango chassis. This performance architecture incorporates a specialized premium Merge X-Pipe assembly along with ultra-smooth mandrel bends and patented multi-core internal geometry. This configuration maximizes exhaust velocity, optimizes cylinder-bank scavenging, and balances pressure pulses to unlock hidden horsepower, sharper throttle response, and enhanced fuel economy across the entire powerband. 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 sleek single split rear exit layout finished with massive 4.5-inch single round, rolled edge angle-cut black chrome premium T-304 stainless steel tips on each tailpipe. 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.
Integrated High-Flow Merge X-Pipe: This premium performance upgrade features an integrated Merge X-Pipe built directly into the plumbing layout. By crossing over the exhaust streams seamlessly, it harmonizes the aggressive rumble of the 6.4L V8 while improving gas flow velocity for maximum modern muscle car performance.
Black Chrome Tip Care & Maintenance: The premium 4.5-inch black chrome finish on this system requires specific maintenance to safeguard its deep, mirror-like luster. Using abrasive metal cleaner or standard stainless steel polishes (such as Borla 21499) is NOT recommended with these specialized black chrome tips. To avoid damaging the finish, simply clean the tips using hot water and a soft microfiber cloth.
Drivetrain & Chassis Architecture: This premium performance exhaust system is precision-tailored out of the box to accommodate the high-performance 4-Door All-Wheel Drive (AWD) Durango SRT SUV chassis. It bolts directly to the factory emission paths behind the catalytic converters, preserving complete emissions compliance while replacing the heavy, restrictive stock exhaust path.
