Kooks 14-19 Chevrolet Corvette Z06/ZR1 3in. H.O. SS GREEN Catted Ultra X-Pipe - OEM Connection

Replacing the midpipe on a 2014-2019 Chevrolet Corvette Z06 or ZR1 is one of the most common exhaust modifications for the C7 platform, and this Kooks Ultra X-pipe is built to handle what these cars put out. Part number 21703420, this is a 3-inch catted X-pipe made from stainless steel with Kooks' GREEN catalytic converters and an OEM connection setup, so it bolts directly into the factory exhaust without cutting or welding.

Kooks builds this X-pipe from stainless steel and includes high-flow catalytic converters in the GREEN series, which means you still get cats in the system while picking up flow over the restrictive stock midpipe. The X-pipe design merges exhaust pulses from both banks, which can help balance exhaust scavenging and produce a more refined exhaust note compared to an H-pipe. At 3 inches in diameter, this pipe is sized to move serious volume on the supercharged LT4 (Z06) and LT5 (ZR1) engines.

The OEM connection means this X-pipe uses the factory flange and clamp points. No fabrication needed. This is not CARB approved, so check your local emissions requirements if you drive in California or other CARB-regulated states.
