Fabspeed Performance Catalytic Converters for 2020+ C8 Corvette

Description

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.

• Two (2) Fabspeed high-flow catalytic converter assemblies with heat blankets

• Direct-fit mounting hardware

• Installation instructions

Product Specs

• 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.

Product Features

• 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.
