About this product

Part #: 817675

Flowmaster's Force II Crossmember-back system for the 1963-1967 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 327 Small Block V8 features specially tuned stainless steel 50 Series Delta Flow mufflers, a Scavenger X-pipe assembly and 2.25" 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 2.25" polished 304S stainless steel tips that exit within the factory cutout bezels. The exhaust system is covered by Flowmaster's Lifetime Limited Warranty. Designed for an easy fit, this system includes all necessary parts and hardware for installation. Note: This system can be used with manifold downpipes #81094 (Manual Trans) or # 81096 (Auto Trans) to create a complete system.
