Description
Overview
The Flowmaster 86-90 Chevrolet Corvette (350) Exhaust System Kit is a complete cat-back exhaust system engineered specifically for 1986-1990 Chevrolet Corvettes running the 5.7L (350) engine. Built as part of Flowmaster’s Force II® series, this exhaust system is aimed at Corvette owners who want real performance gains and a refined tone without a loud, droning cabin. If you’ve been searching to shop for exhaust upgrades that bolt on cleanly and deliver measurable efficiency improvements, this Flowmaster performance exhaust is purpose-built for your car.
The system starts at the factory ball flange at the rear of the vehicle, flowing into a Scavenger Series® Y-collector that splits the flow into a true dual layout. From there, 2.50-inch mandrel-bent aluminized steel tubing carries exhaust into a matched pair of specially designed Delta Flow® mufflers, then finishes with dual 2.50-inch brushed stainless steel tips at each muffler for a clean, factory-integrated look.
Key Benefits
Like all Flowmaster® systems, this catback exhaust is tuned to improve throttle response, power, and mileage. The Force II® calibration produces a moderate exterior tone paired with a mild interior tone, keeping cabin noise down while still delivering a deep, mellow performance sound outside the car. That makes it an ideal exhaust system for drivers who prioritize efficiency and daily-drivability over aggressive volume.

Fitment
This exhaust system kit is designed exclusively for 1986-1990 Chevrolet Corvette models equipped with the 5.7L (350) engine in a 2WD configuration. Because the system starts at the factory ball flange and uses the factory hanger locations, it fits the way the original exhaust did — no cutting guesswork and no fabricated brackets required. The Force II® series and 50 Seriesâ„¢ Delta Flow® muffler design work together to complement the C4 Corvette’s output.
Whether you’re comparing a Flowmaster car exhaust against a Borla exhaust system, a Corsa exhaust, a MagnaFlow exhaust, or a Walker exhaust, this kit stands out for pairing bolt-on simplicity with the balanced tone Corvette owners want. Every exhaust pipe, muffler, tip, and piece of hardware needed for installation is included, so you get a genuinely complete performance exhaust upgrade in one kit.
