Adding the finishing touches to your GMC Sierra’s exhaust system with 2014-2017 exhaust accessories from AmericanTrucks opens up new possibilities for improving your pickup’s performance. 2014-2017 mufflers for the Sierra include superior components made by leading manufacturers like Gibson, in both offset and straight-through pipe configurations. These mufflers are tuned to generate a pulse pounding exhaust note – a deep, aggressive rumble – while avoiding drone inside the cab. They are, of course, also high-flow and can be used with mandrel-bent exhaust systems to improve the removal of waste gases that could otherwise slow the engine with backpressure. Other 2014-2017 exhaust accessories include electronic exhaust cutout systems that let you switch between quiet and earsplitting exhaust notes, and silicon gasket maker that can be used to informally fabricate a needed gasket for leak-proofing your truck’s exhaust system.
