Unlock a more aggressive exhaust tone and improved performance for your 2020-present Corvette C8 & E-Ray with Fabspeed Sport Cats — high-flow catalytic converters engineered to replace the restrictive factory units. These Sport Cats significantly increase exhaust flow over the OEM 700-cell cats while retaining emissions compliance and avoiding check engine lights when properly installed. The result is a deeper, more muscular LT2 V8 sound and measurable gains in horsepower and torque when paired with valved or non-valved exhaust systems. Built with high-quality T304L stainless steel and optimized with oversized 200 CPSI catalyst cores, Fabspeed Sport Cats are a direct, bolt-on enhancement that helps your C8 perform and sound better than stock.
Designed for Chevrolet Corvette C8 (2020 and newer) — compatible with Stingray and E-Ray models.
Direct bolt-on replacement for factory catalytic converters.
Professional installation recommended, especially when combined with other exhaust upgrades.
Two (2) Fabspeed high-flow catalytic converter assemblies with heat blankets
Direct-fit mounting hardware
Installation instructions
Catalyst Core: German-made 200 CPSI high-flow units — significantly more surface area than stock.
Material: T304L stainless steel construction for strength, corrosion resistance, and long life.
Weight Savings: Approximately 9 lbs (4 kg) lighter than stock catalytic converters.
Flow Design: Optimized for performance and emissions compliance without triggering fault codes.
Installation: Bolt-on design uses existing exhaust mounting points for a straightforward fit.
Enhanced exhaust tone: Deeper, more aggressive sound character from the LT2 V8 compared to stock cats.
Improved performance: Dyno tests show gains as high as ~20 HP and ~22 lb-ft torque over stock when paired with valved exhaust (results vary by setup).
High-flow 200 CPSI catalysts: Oversized, high-density catalyst media balance emissions compliance with freer flow.
Bolt-on installation: No cutting, welding, or fabrication required — installs using OEM mounting points.
Weight reduction: Lighter than stock catalytic converters, contributing to reduced rear mass.
Durable construction: T304L stainless steel resists corrosion and elevated exhaust temperatures for lasting performance.
