ive had flowmaster on most of my trucks except my current 97 has a thrush flowmaster knock off. i like the flowmaster force 2 systems as they have a nice little growl to them but are friendly on the highway. but ya everything from the american thunder on a 91 Camaro and a true dual no cats flowmaster 40 setup on a pickup dumped righg after the cab. down to custom diy stuff and the flowmaster force 2. i like magnaflow on smaller engines but not on v8s. gibson has a nice sound also. but as noted above regarding an all steel exhaust they will rot out. if you do go all steel run the truck for a week or 2 then get some exhaust high heat paint and coat the whole exhaust. next morning it will have a smell as your running it but once the smell clears it will last alot longer. i dont even bother with a steel exhaust anymore unless im doing a cheap diy system or a cheap diy repair. stainless steel exhaust is so much better.
