MIA's Description

Upgrade to Long Tube headers on your 2020-23 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. Built from corrosion resistant 304 stainless steel, our headers are TIG welded for strength and durability at our state-of-the-art facility in Streetsboro, Ohio. We stand by our products with a lifetime warranty on materials and craftsmanship, and as always, our products are proudly made in the USA.
