Product Description

The Borla 140646 is an ATAK Cat-Back exhaust for the 2015-2023 Dodge Challenger SRT Hellcat equipped with the MDS (multi-displacement system) cylinder deactivation. ATAK is Borla's most aggressive sound level -- louder and more visceral than the S-Type or Touring, but engineered through Borla's patented straight-through and multi-core technology to remain drone-free inside the cabin. A Merge X-Pipe is built into the system for improved exhaust scavenging and enhanced sound character at all RPMs.

Unlike the 140647 and 140648 variants, the 140646 includes fully functioning MDS valves that preserve the factory cylinder deactivation system. The valve actuators are transferred from the OE exhaust to a matching bracket on the Borla system during installation -- no warning lights, no loss of fuel economy in deactivation mode, no compromises. Tips are not included; the system is engineered to use the factory bezel and valance for a clean, OEM-style tip appearance. Built from T-304 austenitic stainless steel with CNC mandrel-bent tubing. Backed by Borla's Million-Mile Warranty. Made in the USA.
