Kooks Super Street Headers and Ultra-GREEN OEM Connections for 2020 C8 Corvette

Kooks Headers and Exhaust is announcing an addition to The Kooks Super Street Series. These headers are designed to be used with OEM catalytic converters or Kooks Ultra-GREEN OEM Connection Pipes. Part# 21801400, Kooks Super Street Stainless Headers are engineered for optimum fitment and added acceleration performance. These headers are made in high quality 304 grade stainless steel with 3/8” thick flanges, 1-7/8” equal length primaries for maximum horsepower and torque, our patented scavenging spikes and one-piece collectors. The outlet of the headers features 3/8” thick 3-bolt flanges to connect to the OEM Catalytic Converters allowing for a direct bolt-on installation. The kit will include installation hardware and required gaskets. Part# 21803300, Kooks Ultra-GREEN OEM connection pipes, are also made in 304 grade stainless steel with 3/8” thick flanges. Kooks Ultra-GREEN EPA certified cats feature a 304 stainless steel outer body and a high capacity 300 Cell 4-1/2" diameter metallic substrate designed to be used with no tune required. The inlet and outlet are designed to connect directly to the OEM Connections flanges, so they can be used as a direct replacement for the OEM catalytic converters with the OEM manifolds, or the Kooks Super Street Headers. The kit will include installation hardware and required gaskets. After baselining our Z51 Equipped test vehicle, we bolted the Super Street Headers and Ultra-GREEN OEM Connection pipes on in place of the OEM Manifolds and catalytic converters. We returned to the dyno to find that this combination produced an increase of 20+ H.P. and 26+ lb-ft of Torque on the stock tune with NO Check Engine Light.
