Diesel Exhaust Systems — 4″ & 5″ Turbo-Back, 304 Stainless

Seguler turbo-back and cat-back exhaust systems for 6.6L Duramax, 6.7L Cummins, and 6.7L Powerstroke. 304 stainless, 4″ and 5″ diameter, mandrel-bent with TIG-welded hangers. Factory exhaust on a deleted truck necks down to 3″ in places — our 5″ straight-through systems drop EGTs by 150-200°F at highway load. Deeper tone, faster turbo spool, and your EGT gauge stays out of the red on long grades. Includes all clamps, hangers, and gaskets. Fits factory mounting points.
