3-Inch Cat-Connect X-Pipe for 2014-2019 Corvette C7 Z06 and ZR1 for Maximum Exhaust Flow
The Corsa Performance COR21078 3-Inch X-Pipe is a precision exhaust crossover pipe designed to pair with Corsa cat-back exhaust systems on the 2015-2019 Chevrolet Corvette C7 Z06 and ZR1 6.2L LT4. The X-Pipe design balances exhaust pulses between the engine's two cylinder banks for improved scavenging efficiency, broader power delivery, and a more refined, even exhaust note across the RPM range. The COR21078 is manufactured from mandrel-bent T304 stainless steel and is designed for bolt-on compatibility with Corsa's Z06 and ZR1 cat-back systems. It is a purpose-built performance component for C7 Z06 and ZR1 owners who want optimized mid-pipe flow to accompany their Corsa exhaust setup.

Frequently Asked Questions
What is the COR21078?The COR21078 is a Corsa Performance 3-inch T304 stainless steel X-Pipe mid-pipe designed for the 2015-2019 Chevrolet Corvette C7 Z06 6.2L LT4 and 2019 ZR1. It replaces the factory mid-pipe with an X-pipe design for improved exhaust balance and flow.
What does an X-Pipe do compared to an H-Pipe?An X-Pipe crosses the two exhaust banks at a diagonal angle, which improves high-RPM exhaust scavenging and tends to produce a slightly higher-pitched, more refined tone. An H-Pipe connects the banks parallel, which preserves more low-end torque and a deeper sound character. The COR21078 uses the X-Pipe design for top-end emphasis.
Does the COR21078 require any other Corsa components to work?The COR21078 is designed to pair with Corsa cat-back exhaust systems for the C7 Z06 and ZR1. It can also be used as a standalone mid-pipe upgrade with the factory mufflers, but is optimized when paired with a Corsa cat-back system.
Does the COR21078 require a tune?No. The COR21078 is a bolt-on mid-pipe component that does not require an ECU tune. However, adding exhaust components may make additional power available that a tune could optimize.
Is the COR21078 compatible with headers?The COR21078 is designed to connect from the factory header or converter collector to the Corsa cat-back system. Verify connection dimensions with your specific header setup before ordering if running aftermarket headers.
What warranty does Corsa offer on the COR21078?Corsa Performance backs the COR21078 with a limited lifetime warranty against manufacturing defects in materials and workmanship.
Is the COR21078 legal in California?No. This component is not CARB compliant and is for off-highway use in California. It is legal for street use in all other US states.
Does the COR21078 fit the C7 Stingray?No. The COR21078 is engineered for the larger 6.2L LT4 in the C7 Z06 and ZR1. The base C7 Stingray uses a different engine and exhaust routing that requires a different part number.
Installation Instructions
- Safely raise the Corvette on a lift or jack stands and allow all exhaust components to cool completely.
- Disconnect the factory mid-pipe or existing mid-pipe at both the header collector and the cat-back connection points.
- Remove the factory mid-pipe from all mounting and hanger locations.
- Position the COR21078 X-Pipe into place, connecting at the header collector outlets.
- Connect the downstream end to the cat-back system inlet.
- Secure all connection hardware and verify all mounts are properly engaged.
- Start the engine and inspect for exhaust leaks at all connection points before driving.
