Checked out some new trucks while at Dealership today. The White High Altitudes have Flowmaster with Double Wall tips. The dark Trucks are from an unknown company had Glass packs about the size of a Liter soda bottle, Y pipe split into skinny pipes with crinkled bends with tips that looked like soup cans. The Aluma coat was flaking off and rusting ,can't believe someone would install that junk on a new truck
