Borla Challenger S-Type Cat-Back Exhaust System - 140677

Borla Part #140677 is a premium S-Type Cat-Back™ Exhaust System engineered for the 2015–2023 Dodge Challenger SRT 392, 392 Hemi, and Scat Pack 392 equipped with the 6.4L V8 and MDS (cylinder deactivation).

This system includes MDS Valve Simulators, which eliminate the factory MDS valves to ensure maximum exhaust flow at all times while preventing warning lights or error codes. It's the ideal choice for drivers who want consistent performance and sound without variable valve restrictions.

A Merge X-Pipe enhances exhaust scavenging for improved performance and a cleaner, deeper sound. The Borla S-Type tone delivers a balanced, sporty exhaust note—aggressive when accelerating, yet refined with no interior drone.

This system does NOT include tips and is designed to reuse the factory bezel/valance and factory tips.

Constructed from high-grade T-304 stainless steel, this Cat-Back™ system offers exceptional durability, corrosion resistance, and precision fitment thanks to CNC mandrel bending.

Backed by Borla’s industry-leading Million-Mile Warranty.
