MRT designed a premium exhaust system for the all-new 4th Gen GMC Sierra that increases your truck's power, fuel efficiency AND boosts your driving experience! The MRT ToughTruck catback is MRT's loudest exhaust for the Sierra 1500 full size pickup. This side-exit exhaust is handcrafted in corrosion resistant T304 Stainless Steel and sounds amazing -- you can actually hear the gear changes, there's a strong presence at steady state that's not obnoxious or offensive and you have to love hearing the burbles as you decel. In fact, when you hear the exhaust, you expect to see a muscle car and then you're surprised when you see it's a next-gen Silverado...so much fun!
This system is made from 3" mandrel bent exhaust tube and has a 4" double wall, polished T304 stainless steel tip with beveled edges. You can also upgrade your tip style to a black matte finish for some extra truck appeal. Team MRT engineered a tough-sounding, corrosion resistant, quality performance system with a Tough Truck sound that increases your Sierra's capabilities with an upgraded, side exit exhaust system built in the USA and made to last.
If you're looking to give your GMC Sierra 1500 a moderate increase in loudness packed with a whole lot of performance, check out the MRT Deep and Mellow Cat-back. MRT Part #92T111G
