Free from packing and made to provide a straight through, strong flow of exhaust, the 2014-2017 Sierra mufflers stocked by AmericanTrucks will give your pickup a powerful new voice without lessening the effects of its enhanced exhaust and aspiration system. You can take your pick of center/center, offset/center, or offset/offset inlet and outlet fittings, depending on the design of your specific system. These high quality mufflers are designed to be the finishing touch for any Sierra exhaust system from the appropriate model years, and are built from stainless steel with a limited lifetime warranty. They are fabricated to produce a deep, commanding rumble as your truck’s exhaust note, while their internal architecture suppresses any droning that might occur in the cab. Many of them are even made in the USA so they not only work great but support American business, too.
