The Stainless Works long-tube headers for 2001–2004 C5 Corvette use 1-7/8" primary tubes and a 3" center section with an X-pipe and catted leads. CNC mandrel-bent 304 stainless construction, 3/8" laser-cut flanges and full TIG welding support durability and flow. These bolt-on headers install without cutting and have demonstrated notable rear-wheel gains on highly modified engines, suited for big-inch, forced-induction or nitrous setups.
