Every system is individually engineered and dyno-tested for each application and includes all required mounting hardware. All tubing is mandrel bent for superior exhaust gas flow, and is a key to the system's performance improvements. Both mufflers and tubing are fabricated from 409 stainless steel for corrosion resistance.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eAmerican Thunder\u003c\/strong\u003e\u003cbr\u003eLooking for the famous, full-on \"Flowmaster tone?\" Look no further.

This results in increased horsepower, torque and fuel economy, along with reductions in exterior sound levels and interior resonance. These three deflectors function properly only when they've been precisely placed and welded to exact specifications. Together they provide superior reductions in exterior sound levels as well as resonance transmitted through the exhaust system and into the vehicle.","brand":"Flowmaster","offers":[{"title":"Default Title","offer_id":48213755396354,"sku":"FLO-817312","price":1049.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/0618\/0354\/files\/db310b0e14355f137b9df15171d8dd51_2.jpg?v=1784983557","url":"https:\/\/www.lethalperformance.com\/products\/flowmaster-99-04-mustang-409ss-american-thunder-catback-w-40-series-delta-flow-muffler","provider":"Lethal Performance","version":"1.0","type":"link"}
