Chevrolet Suburban Performance Exhaust - Stainless Works - 1-7/8in Primaries High-Flow Cats X-Pipe - `15-`20 is a direct-fit performance header and X-pipe assembly for 2015–2020 Chevy Suburban (also compatible with Tahoe/Yukon 5.3L & 6.2L applications). It is designed to improve exhaust flow and produce a more aggressive, refined tone while retaining high-flow catalytic converters for emissions compliance.

This Stainless Works system uses CNC mandrel-bent 1-7/8" primary tubes that merge into 3" slip-fit collectors and high-flow catted leads which flow into 3" lead pipes and an X-pipe. Constructed from corrosion-resistant 304 stainless steel and TIG welded for long-term durability, the kit is built for a close fit to factory flanges and mating Stainless Works catback systems. Benefits include reduced restriction, better scavenging through the X-pipe crossover design, solid fitment with performance connect capability, and components manufactured in the USA with a lifetime warranty on materials and craftsmanship.
