Product Details
AUTOSPEED C8 STINGRAY CORVETTE PERFORMANCE SERIES CATBACK EXHAUST
Our design objective was clear: NO COMPROMISES! Every aspect of the exhaust has been
carefully imagined, engineered, and manufactured to reality. Our team set out to build a
cat-back exhaust that would set the standard in the C8 market. 304 Stainless components
are expertly TIG welded throughout, ensuring you are purchasing a product of the highest
quality. A brushed machine finish is an extra touch, letting you know your product has been
made with American Pride. A Cast X-Pipe creates an ultra-smooth transition while
maximizing scavenging effects to produce power. Our mufflers feature a 3" straight-through
resonated design to eliminate restrictions while producing a loud, deep, sophisticated
exhaust note. With sound valves closed, the flow path is routed through three separate
chambers, eliminating drone and resulting in the perfect sound at all throttle positions.
Available in three tip options, allowing you to personalize your supercar's look.
DESIGN
• Symmetry: Your LT2 is symmetrical; we painstakingly measured the engine bay to create a
fully symmetrical design for the left and right banks.
• Designed to be 100% bolt-on. No cutting, welding, or fabricating required.
MATERIAL, FINISH, CONSTRUCTION
• 304 Stainless Steel used throughout: flanges, flex joints, valve bodies, mufflers, hangers,
clamps, and tips.
• Machined brushed finish components and tubing.
• TIG welded using back purging techniques versus competitors’ inferior MIG welding.
FLANGES
• CNC milled from billet stainless for a precision fit to the exhaust manifolds.
• Superior to competitors’ waterjet or plasma-cut flanges, which are typically rough, warped,
and poor-fitting.
TUBING
• Made by RATH GIBSON, the leading USA manufacturer of precision welded tubing.
• All tubing is 304SS with 0.065" wall thickness, 3" diameter for main tubing, and 2.25" for
inner tips.
• CNC mandrel bent for constant diameters and quality-checked with state-of-the-art
Hexagon Metrology Romer Arms.
FLEX JOINTS
• 100% 304 Stainless Steel, including the end caps and collars.
• Features a smooth interlock interior for maximum flow versus competitors’ corrugated
interiors.
X-PIPE CROSSOVER
• Stainless Steel Cast X-Pipe for an ultra-smooth transition.
• Maximizes scavenging effects to produce the most power.
MUFFLERS
• Heavy wall stainless bodies with a 3" straight-through design for maximum horsepower.
• Internal triple-chambered sound absorption eliminates drone with valves closed.
VALVES
• Rattle-free, patent-pending design.
• Custom actuator holders made from billet aluminum act as heat sinks to prolong the
actuator motor's life.
