About this product

Part #: 817720

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 DOR (Dual Out the Rear) system for the 454ci V8 models (or high HP small blocks) features specially tuned stainless steel 50 Series Delta Flow mufflers, a Scavenger X-pipe assembly and 2.50" 409S stainless steel tailpipes. Like all Flowmaster systems the pipes are all mandrel bent to reduce any restrictions and maximize performance. The system finishes with 2.50" polished 304S stainless steel tips that exit within the factory cutout bezels. The exhaust system is manufactured in the USA and is covered by Flowmaster's Lifetime Limited Warranty. Designed for an easy fit, this system includes all necessary parts and hardware for installation.
