Borla ATAK® Cat-Back™ Exhaust System

For 2015-2023 Dodge Challenger SRT 392 & Scat Pack 6.4L (Part #140678)

Product Description

Unleash the true fury of your 392 Hemi! This high-performance 2.75" diameter Cat-Back™ system includes an integrated Merge X-Pipe designed to maximize exhaust velocity, increase performance, and dramatically improve your exhaust tone.

It features Borla's most aggressive ATAK® (Acoustically-Tuned Applied Kinetics) sound level. Designed for high-performance purists who want an uncompromising Mopar growl, it delivers an earth-shattering, head-turning roar on the outside while retaining clarity and avoiding the drone typically found in louder exhausts inside the cabin.

BORLA® Cat-Back™ exhaust systems feature patented straight-through and multi-core technology designed to unleash hidden horsepower. Each system is built from premium, high-quality T-304 austenitic stainless steel, superior to T-400 series knockoffs (such as 409), to give you the absolute best in performance and durability.

⚠️ IMPORTANT FITMENT NOTES:

MDS Valve Simulators Included: This system is equipped with active valve simulators which ELIMINATE the MDS (cylinder deactivation) valves. The factory valve actuators will be transferred from your O.E. exhaust to a bracket on the BORLA® exhaust. This avoids warning lights on the dash while providing maximum flow at all times.

Exhaust Tips NOT Included: This system is designed to retain and reuse your factory exhaust bezels/valance for a seamless, stock-like rear appearance.
