I have a 99 cobra and had a quick exhaust question. I was wondering if I changed out the Mufflers on the car would I get close to the same sound that I would out of a cat back system? Hypothetically, Lets say I switched to flowmasters american thunder mufflers, would I get close to the same sound that I would out of the full catback? I am a little low on cash and would be happy if I could get the sound I am looking for, relatively inexpensively. Thanks for the help.
