This all stainless steel exhaust system features our exclusive design 80 Series(TM) Crossflow muffler, all mandrel-bent dual 2.50-inch pipes including an H-pipe crossover for a deep smooth tone that also minimizes any back-rap on deceleration. The dual 2.50-inch stainless steel tailpipes provide a deep rich sound and optimum performance. This crossmember-back 409S stainless system gives these classic muscle cars a moderate tone inside and out. Using the crossflow design, this exhaust places the muffler in the factory location behind the rear axle retaining full ground clearance under the car while offering all the performance benefits of a full dual exhaust system. The system includes all parts, hardware and illustrated instructions, and like all Flowmaster stainless steel street products, it includes our Limited Lifetime Warranty.\u003c\/p\u003e\u003cp align=\"left\"\u003eFlowmaster operates the only exhaust Research \u0026amp; Design facilities of its kind in the world, centered around the SuperFlow SF-7100 engine dynamometer complete with E.C.A. (engine cycle analysis) equipment and also SuperFlow chassis dyno's. Through use of these dyno's, Flowmasters engineering staff can track the complete engine cycle in millionths of a second and can obtain exact technical data of each degree of cam rotation, from induction to the tip of the exhaust system, while also showing the power numbers that really matter, the power numbers to the ground. Flowmaster also utilizes Spectrum Analyzers to fine tune the sound of each of the eleven different series of mufflers that Flowmaster currently offers, both for peak performance and just the right sound levels and tones.
