2014 GMC SIERRA BADASS TRUE DUAL EXHAUST

14 GMC Sierra 5.3 We installed a true dual exhaust with forged x pipe with a set of our super 40 Flowmaster into our exclusive tuck away style tailpipes and our very own Viper tips. This system is balanced and equalized to give the truck a smooth rich tone with no interior drone or resonation. This system will produce 18 hp and 1.5 mpg gains. AFE Stage 2 intake produces 11 hp and 23 torque with 1 mpg.
