Borla Replacement Muffler - Chevrolet Silverado 1500 (T1) - 3.5in Sound Level Conversion 2019
This Borla 3.5in replacement rear muffler converts the Borla cat-back for the 2019 Chevrolet Silverado 1500 (T1) 6.2L V8 between sound levels. The S-Type muffler replaces the Polyphonic Harmonizer in a Borla ATAK system for a quieter, sporty note, while the ATAK Polyphonic Harmonizer replaces the small rear muffler in a Borla S-Type system for Borla's most aggressive sound.
Note: For use with the Borla 2019 Silverado 1500 cat-back systems only; it does not fit the factory exhaust. Designed around the US left-hand-drive Silverado. Australian Silverados are converted to right-hand drive locally, so please confirm tailpipe routing, fuel tank, spare wheel and towbar clearance with our team before ordering. Suits the 6.2L petrol V8 only, not the diesel. Installation by a professional is recommended.
