Upgrade to Long Tube headers on your 2020-21 Chevy Silverado or GMC Sierra HD with this system from Stainless Works. Unleash that 6.6L motor with 1-7/8" or 2" primaries that flow into a 3" collector with an integrated merge spike. This system comes with high flow cats and your choice of either a Y-Pipe or X-pipe for a simple bolt-on install.

Out of the box this system fits the 6.6L gas motor in both 2 wheel and 4 wheel drive. It fits all cab/bed configurations and can connect to the stock exhaust or Stainless Works Legend or Redline catback systems for a True Dual Exhaust.
