Quote from company:
"Stainless Works is the single resource for all your Corvette header and exhaust needs. We offer multi-platform header designs and optional primary-tube sizes to satisfy a broad set of special needs. We provide the highest level of quality and workmanship in bringing you the best performance and sound level for your cherished vehicle."
Stan's Tri-Y headers were specifically designed to help C3s scavenge more efficiently. While four-tube headers are well suited for some applications, our Tri-Y design is significantly more effective on most street and off-road applications.
Before you install our headers, please check out their quality-you won't find a better-built header anywhere. Look inside the collectors; there is no wire or "bee bees" from the welding, sticking to everything. Our headers are gas-welded inside which allows them to last nearly twice as long as headers with wire-feed welding; this is because gas welding flexes more. (Think about how the engine twists on acceleration and shakes while idling. All of this motion is transmitted through the exhaust system.)
Our header flanges are ground flat and deburred so that they are smooth inside. They utilize the entire machined surface of the head for a gasket surface (not an O-ring gasket area like other headers). A flat header surface won't warp like O-ring ports do.
Our headers are clearanced for the header bolts and box-end wrenches. Can you imagine that? Someone in the business is concerned about the ease of accessing parts and fasteners. We think that's unique.

SLP Performance Parts
SLP offers long-tube header packages that fit '97-'04 C5 and '05-'10 C6, Grand Sport, and Z06 Corvettes. Our C5 headers feature 13/4-inch main primary tubes flowing into two 3-inch, high-flow venturi collectors. Our C6 headers feature 13/4-inch main primary tubes flowing into two 21/2-inch, high-flow venturi collectors. Our C6 Z06 headers feature a 4-into-2-into-1 design with 13/4-inch main primaries flowing into two 21/4-inch secondary primaries, which then flow into one 3-inch, high-flow collector.
Our headers are hand-crafted from mandrel-bent 409 stainless steel and then ceramic coated to keep heat in, exhaust velocity up, and underhood temperatures down. The rest of the system is made from high-quality mandrel-bent 304 stainless steel.
Included in each package are a pair of 3-inch, high-flow catalytic converters, which flow into a fully integrated PowerFlo-X crossover assembly (3-inch for the C5 and 21/2-inch for C6) for unrestricted flow. Each package is fully compatible with all stock emissions-control equipment and uses OE flanges for a perfect fit and proper bolt retention. All necessary installation hardware and detailed installation instructions are included, along with our lifetime warranty and performance guarantee.
