My experience with Dodge Auto Supply was excellent when ordering the Catted Midpipe Kit for my 2020 Durango SRT. The ordering process was smooth, and the product information was accurate. Shipping was fast, and tracking updates were consistent. The midpipe kit arrived in perfect condition and looked very high quality. The stainless finish is excellent, and the welds are clean and professional. Installation at my performance shop was quick, and fitment was perfect. After installation, the exhaust note became noticeably deeper and much more aggressive during acceleration. The truck feels stronger and more responsive now. This is a great performance and sound upgrade.
