American Thunder SS Crossmember-Back Exhaust System","description":"Flowmaster® is proud to introduce our American Thunder® dual exhaust system for 1967-1974 Chevrolet Camaro, Pontiac Firebird and 1968-1974 Chevrolet Nova's. This all stainless steel exhaust system features our exclusive design 80 Series™ 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.\nFits 1967-1974 Chevrolet Camaro, Pontiac Firebird with V8 engine. 2.50 inch Stainless Steel - Moderate sound\nConvertible models require 3\/8-inch of shims on the factory X-brace for clearance of the exhaust tubing.\n\u003cul\u003e\n  \u003cli\u003eIncludes Hangers and Hardware for Easy Installation\u003c\/li\u003e\n  \u003cli\u003eH-pipe Crossover for Maximum Power and Deep Tone\u003c\/li\u003e\n  \u003cli\u003e80 Series Cross-flow Performance Muffler\u003c\/li\u003e\n  \u003cli\u003eMandrel-bent Stainless Steel Tubing\u003c\/li\u003e\n  \u003cli\u003eModerate Exterior Exhaust Tone\u003c\/li\u003e\n  \u003cli\u003eStainless Steel Construction\u003c\/li\u003e\n  \u003cli\u003eLifetime Limited Warranty\u003c\/li\u003e\n  \u003cli\u003eMaximum Ground Clearance\u003c\/li\u003e\n  \u003cli\u003eCrossmember-Back System\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\nFitment:\u003cbr\u003e\n1967 Chevrolet Camaro\u003cbr\u003e\n1967 Pontiac Firebird\u003cbr\u003e\n1968 Chevrolet Camaro\u003cbr\u003e\n1968 Chevrolet Chevy II\u003cbr\u003e\n1968 Pontiac Firebird\u003cbr\u003e\n1969 Chevrolet Camaro\u003cbr\u003e\n1969 Chevrolet Nova\u003cbr\u003e\n1969 Pontiac Firebird\u003cbr\u003e\n1970 Chevrolet Camaro\u003cbr\u003e\n1970 Chevrolet Nova\u003cbr\u003e\n1970 Pontiac Firebird\u003cbr\u003e\n1971 Chevrolet Camaro\u003cbr\u003e\n1971 Chevrolet Nova\u003cbr\u003e\n1971 Pontiac Firebird\u003cbr\u003e\n1972 Chevrolet Camaro\u003cbr\u003e\n1972 Chevrolet Nova\u003cbr\u003e\n1972 Pontiac Firebird\u003cbr\u003e\n1973 Chevrolet Camaro\u003cbr\u003e\n1973 Chevrolet Nova\u003cbr\u003e\n1973 Pontiac Firebird\u003cbr\u003e\n1974 Chevrolet Camaro\u003cbr\u003e\n1974 Chevrolet Nova\u003cbr\u003e\n1974 Pontiac Firebird\u003cbr\u003e\n\u003cbr\u003e\n\u003cbr\u003e\nAir Freight Prohibited: false\u003cbr\u003e\nNot Carb Approved: false\u003cbr\u003e\nCarb Acknowledgement Required: true\u003cbr\u003e\nLtl Freight Required: false\u003cbr\u003e\nProp 65: Y\u003cbr\u003e\nPart Type: automotive\u003cbr\u003e\nEpa: N\/A\u003cbr\u003e\nUnits Per Sku: 1","brand":"Flowmaster","offers":[{"title":"Default Title","offer_id":49296456843483,"sku":"flo817104","price":1249.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0797\/8559\/1003\/files\/7829799be42bd8f5fcfbc5c081582984L.jpg?v=1789163592","url":"https:\/\/hnbperformance.com\/products\/flowmaster-67-74-camaro-nova-2-5in-american-thunder-ss-crossmember-back-exhaust-system","provider":"Hellnback Offroad \u0026 Performance","version":"1.0","type":"link"}
