Give Your 5.7L Hemi The Savage Growl It Deserves
The B535-C535 Savage is a 3 inch catback exhaust system built for the 2019 to 2026 RAM 1500 with the 5.7L Hemi V8. Constructed from mandrel bent T304 stainless steel, the Savage catback replaces the factory system from the catalytic converters back, opening up flow and unleashing a deep, aggressive V8 tone that the factory exhaust holds back. Thermal R&D tunes the Savage muffler with its True Helmholtz Technology to control cabin drone at highway speed while keeping the aggressive growl under acceleration that Hemi owners want. The system bolts to the factory hanger locations for a straightforward install with no cutting or welding required.
