Stainless Works 1-7/8 Inch Long Tube Headers with Catted X-Pipe for C6 Corvette Base and Grand Sport
These Stainless Works long tube header kits are designed for C6 Corvette Base and C6 Corvette Grand Sport owners running the LS2 or LS3 who want a complete header-to-mid solution. Both options use 1-7/8" primaries and include a matched 3" catted X-pipe/center section, while retaining a factory-connect style rear pairing at the OEM axle-back connection point.

Why Stainless Works Leads
- Complete, matched layout (headers + high-flow cats + X-pipe/center section) designed to fit the C6 undercarriage cleanly
- 304 stainless construction built for repeated heat cycles and long-term corrosion resistance
- Factory-connect approach at the rear, so you can plan an axle-back without reinventing the entire system
Benefits
- 1-7/8" primaries are a proven size for strong street performance on LS2/LS3 C6 setups
- Matched catted X-pipe included, reducing guesswork when pairing mid-pipes and rear sections
- Creates a long-tube foundation for common supporting mods (intake, cam, heads, and other airflow changes)
What to Expect After Installation / Use
Expect increased exhaust volume and a sharper tone versus stock manifolds. Long tube headers are a labor-intensive install on the C6 platform, and tuning is commonly performed after header changes depending on your setup and local requirements.
