I have a 96' Discovery and I'm thinking of replacing the stock exhaust. I've found Borla and NRP. Does anyone have either of these systems installed and what do they sound like? I've heard that the Borla is kind of loud. I don't want to end up with something that will drone at highway speeds. Right now I only have the stock center muffler in place because my rear resonator rusted through and was rattling so I had it removed. I've also thought of replacing the center(main) muffler with a Ravin muffler from Midas. It is supposed to be similar to a Flowmaster but with a more mellow sound.
