Omni LT1 Street Package (Stage 2)

The Omni LT1 Street Package builds upon the Foundation Package by adding one of the most effective naturally aspirated bolt-on upgrades available—long-tube headers and a performance X-pipe.

By improving exhaust flow and pairing it with a cold air intake, flex fuel conversion, and a custom dyno calibration, this package unlocks even more horsepower throughout the entire RPM range. The result is stronger acceleration, improved throttle response, and an aggressive exhaust note while maintaining the drivability expected from a professionally engineered combination.

Designed for customers who want more than basic bolt-ons but still expect OEM-like reliability, the Street Package delivers a noticeable increase in performance both on the street and at the track.
