I'm looking for a good performance exhaust for my truck. I have a 95 k1500 4X4 with a 5.7 liter motor extended cab and a short bed. I am checking out the TFX systems. Does anybody know how they sound. I also want to makes sure that I get good throaty muscle car sound. Or is the only exhaust that I can get that will give me a cool sound going to be a flowmaster.
