Show original supplier description
The Cornerstone Performance Stainless Midpipe System is engineered to enhance the exhaust note of your 2018-2021 Jeep TrackHawk 6.2L, 2012+ Jeep SRT8 6.4L, or 2021+ Dodge Durango 6.2L. Constructed from durable 3-inch stainless steel, this midpipe system features smooth mandrel bends that promote increased exhaust flow and optimized performance. The design allows it to bolt directly to the stock exhaust manifolds, ensuring a seamless integration with the existing exhaust system and maintaining the factory connection point in front of the X-pipe. Installation is straightforward and requires no drilling, with all necessary hardware included. This midpipe system is proudly manufactured in the USA. Please note that these pipes are not street legal in the United States for use on DOT roads as they violate the Clean Air Act by removing federally compliant catalytic converters. They are intended for race car customers for track use only in sanctioned events. Tuning or anti-foulers will be required to avoid Check Engine Lights (CELs).
