Replacing the down pipe between the headers and the catalytic converter is especially urgent in turbocharged GMC Sierras, where the addition of high-flowing aftermarket 2007-2017 down pipes produces notable gains in power. Fabricated from long-lived, strong materials like T-304 stainless steel, the down pipes you’ll find on AmericanTrucks are carefully chosen to give the best results for your machine’s performance. 2007-2017 catted down pipes offer big flow increases while including the catalytic converters that make the system using them completely street-legal in most states. If you’re planning on using the truck only on the track or the trail, there’s no reason not to add a 2007-2017 off-road down pipes kit, deleting the catalytic converters to squeeze out the last few drops of power and sound from your Sierra while rendering it illegal to use on road.
