Deep and Mellow Single Exhaust System with Polished Tip; Side Exit (19-25 5.3L Sierra 1500)Find parts that fit my vehicle

Description. Meet the best aftermarket accessory for the redesigned GMC Sierra light-duty pickup truck. The MRT Deep and Mellow catback is a side exit exhaust that replaces the Sierra 1500 factory exhaust with a handcrafted, corrosion resistant T304 stainless steel 3" exhaust tube that sounds amazing. This side-exit exhaust increases the sound level versus stock without causing drone so you experience a subtle hum at steady state driving and can hear the exhaust at idle and on engine revs. Also, the larger rear split tube diameter improves exhaust air flow and gives you a nice uplift in performance and fuel economy improvements.

This system has a 4" double wall, polished T304 stainless steel tip with beveled edges which can be upgraded to a black matte finish for some extra truck appeal. Team MRT engineered a deep and mellow exhaust sound to advance your Sierra driving experience and complements the design and style of this latest addition to the GMC family.

If you're looking to give your GMC Sierra 1500 a greater increase in loudness that is packed with a whole lot of performance, check out the MRT Tough Truck Cat-back.MRT Part # 92T106.
