anybody tried a supertrapp on their burb?
I've run Supertrapp mufflers on all my vehicles in the past(98 camry,69 le mans,etc...) I was wondering if anyone had tried one on their 5.7 gasser? I havent had a good look at what I have as far as I know I have a flowmaster with two inlets and one outlet.does that mean I have two cats? If so,am i able to run both to a Y and to a single 5 inch supertrapp or run duels all the way back to two 4 inch supertrapps? I live in cali. so i dont know if duels are legal. also looking for some long tube headers that are 50 state legal,anyone heard of such a thing? any help appreciated. I have a 97 k1500 burban 5.7
