What’s the best accessory for the 4th Gen GMC Sierra to increase appearance and power? An MRT aftermarket exhaust handcrafted in the USA and worthy of an All American truck. The MRT Deep and Mellow catback is a side exit exhaust that replaces the OE GMC Sierra exhaust system 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 for your GMC Sierra so you perform like a rock (and sound solid as well) as you find new roads to experience.
