Special thanks to Kyle for bringing us his lowered 2015 GMC Sierra. Last week we mounted and balanced his new 22-in wheels and Nitto NT-420S tires. But Kyle wasn’t done with his Sierra, as he had a particular exhaust sound in mind. We turned his vision into reality after welding together a full 3-inch stainless dual exhaust system using a 3-in H-pipe, a pair of 3-in Borla Exhaust XR-1 race mufflers, and 3-in turndowns. After connecting this true dual exhaust setup to his 5.3L with long-tube headers, Kyle has an aggressive sound that is truly unique.
