Show original supplier description
The Solo Performance MACH-X MDS Automatic CAT Back Exhaust Kit is engineered to deliver a raw American muscle sound from the outside while maintaining a refined, non-invasive exhaust note within the cabin for your 2008-2014 Dodge Challenger R/T 5.7L Hemi with an automatic transmission. This kit utilizes 2 1/2" mandrel-bent stainless steel tubing and a dual inlet/dual outlet MACH-X muffler, measuring 14" long with a 4" x 9" body. The "true X" design of the muffler is crafted to calm interior noise and smooth out rough RPM ranges, providing a free-flow system. Designed with fit, form, and function as cornerstones, this exhaust kit includes the muffler, exhaust pipes, clamps, and all necessary hardware for installation. A key feature for automatic transmissions is the inclusion of J-pipes specifically developed to cancel out the drone commonly associated with the Multi-Displacement System (MDS). It is important to note that these J-pipes were tested on a stock vehicle, and other engine modifications may require adjustments for optimal performance. This specific kit is for the 2008-2014 Dodge Challenger R/T MDS Automatic models. Buyers can choose between the "No Tips" option, or kits that include Dual Round or Dual Square exhaust tips. The tail pipe assemblies are constructed from 3" mandrel-bent stainless steel and feature a ball and flair front connection for easier exhaust tip adjustment.
