Ya, there basically a cheap flowmaster knockoff. the place that did my truck put the bigger mufflers on (not the 1 chambers) and they sound really nice. For the price i would use them as they sound just as good if not better than the flowmasters and a not even half the cost. I googles it and found the thunderbolt V-force single chamber muffler for like $25.
