STILLEN manufactures our high performance headers from varying materials according to application parameters. All of our uncoated headers are stainless steel for long life and corrosion resistance. Our ceramic coated headers are for those who want an additional thermal barrier to lower engine bay temperatures as well as excellent stain and rust resistance. These hand crafted shorty headers do not require the removal of the catalytic converters.
Headers are available in the following materials:
- 304 Stainless Steel - Maximum oxidation and corrosion resistance, excellent shine
- 409 Stainless Steel - Excellent corrosion resistance, may develop light surface discoloring
- Ceramic Coated - Provides a thermal barrier which reduces radiated heat into the engine bay, excellent stain and rust resistance.
Installation should be done by a qualified mechanic with proper tools and a lift. This is not a backyard bolt on. These headers do not remove the cats, but are not 50 state legal, check your area's regulations. Complete the performance upgrade with STILLEN's new race pipes.
