Overview

Flowmaster's Force II Cross Member Back system for the 1970-1973 Chevrolet Corvette is perfect for the person looking for a moderate exterior and mild interior exhaust tone, with all of the performance benefits that you would expect from Flowmaster. This bolt-on Dual Out Rear system for the 5.7L V8 features 50 Series Delta Flow mufflers, a Scavenger X-pipe assembly and 2.25 in. tailpipes. Like all Flowmaster systems, the pipes are all mandrel bent to reduce any restrictions and maximize performance. The system finishes with rectangular polished 304S stainless steel tips that exit in the factory cutout bezels. The exhaust system is manufactured out of 409S stainless steel and is covered by Flowmaster's Lifetime Limited Warranty. Designed for an easy fit, this system includes all necessary parts and hardware for installation. Note: Can be used with manifold downpipe kits #81098 (Manual trans.) or #81095 (Auto trans.) to create a complete system.

Features:

  • Stainless Steel Construction
  • Dyno Tuned For Maximum Performance
