Unlock the performance potential of the twin-turbo LT7 with the Forza Motor Works C8 ZR1 Stage 1 Performance Bundle.
The factory C8 Corvette ZR1 is already an exceptionally capable platform, but the restrictive factory catalytic converters and factory calibration leave significant performance on the table. This package combines freer-flowing intake and exhaust hardware with the HP Tuners components required to unlock the factory ECM for custom calibration.
SOUL Performance Competition Catless Downpipes
Large-diameter 3.5" construction designed specifically for the C8 ZR1
Eliminates the restrictive factory catalytic converters
Improves exhaust flow, turbo response, sound, and overall performance
SOUL reports maximum gains of more than 100 WHP and 130 lb-ft of torque in portions of the powerband during independent testing
Approximately 32.5 lbs lighter than the factory components
Hand-built in the USA from T304L stainless steel
Halltech Super Hornet Cold Air Intake
High-flow intake system developed for the C8 ZR1
Massive dual-filter design with more than 600 square inches of filtration area
Molded velocity stacks and reverse-flow funnels designed to maintain smooth airflow through both MAF sensors
Increased airflow without requiring permanent vehicle modifications
Designed to work with the factory turbo inlet ducting
HP Tuners E68 ECM Upgrade Service
Required to enable custom tuning of the factory Global B E68 ECM
Original ECM is upgraded by HP Tuners
Allows supported calibration, data logging, reading, and writing through the OBD-II port after the ECM is returned and installed
10 HP Tuners Universal Credits
Required to license the C8 ZR1 E68 ECM through HP Tuners
Allows the upgraded ECM to be licensed for custom calibration
The LT7 responds extremely well to increased airflow and reduced exhaust backpressure. The SOUL Competition Downpipes remove one of the largest restrictions in the factory exhaust system, while the Halltech Super Hornet increases available intake airflow to the twin turbochargers.
Pairing these modifications with full HP Tuners ECM access gives your calibrator the ability to optimize boost control, fueling, ignition timing, torque management, and other critical engine parameters for your specific vehicle and fuel.
Rather than combining individual components that may or may not work together properly, the Forza Stage 1 Package provides the core hardware and tuning access needed to build a properly calibrated high-performance C8 ZR1.

Custom ECU calibration is not included unless specifically selected or stated at the time of purchase.
The factory ECM must be removed and sent to HP Tuners for their E68 Global B upgrade service before it can be custom calibrated through HP Tuners VCM Suite.
Additional tuning hardware or software may be required depending on who is performing the calibration.
SOUL Competition Downpipes eliminate the factory catalytic converters and are intended for competition/off-road applications where legally permitted. Buyer is responsible for determining compliance with applicable federal, state, and local emissions regulations.
