C8 Corvette ZR1 Sport Racing HJS German Catalytic Converters

The C8 ZR1 is already a 1064HP beast—but stock restrictions choke it's true potential. FABSPEED MOTORSPORT USA's ULTRA High-Flow GERMAN Imported Racing Catalytic converters are 100% PROVEN in GLOBAL MOTORSPORTS WEC/IMSA competition and engineered to free the fury. Designed with the ultimate catalytic converters rated at 1200HP each, Fabspeed employs (2) 200-cell EMITEC HJS tri-metallic sport cats for the C8 ZR1. The Fabspeed HJS German racing catalytic converters FLOW 90 to 92% of a straight pipe to dramatically reduce backpressure thereby maximizing exhaust flow, turbo spool, twin turbocharged exotic whistling noises and throttle response. Fabspeed HJS Emitec C8ZR1 catalytic converters achieve all these results WHILE being EPA Compliant and European Homologated and European Certified and TUV approved. More power than illegal catbypass pipes as well. 

Crafted from aerospace-grade T304L stainless steel, Fiber Optic Laser and back purged TIG welded for maximum durability, this upgrade delivers a deeper, more aggressive tone while saving significant weight. Saves -20 pounds -9.1KG, while unlocking real horsepower gains. Expect 100% guaranteed quicker turbo spool-up/spin up transient response, a ferocious growl, and dyno-proven performance increases across the RPM range.
