I have researched, MagnaFlow, Flowmaster, Borla, and Corsa. From shops that I have talked to, everyone wants to with a cat back setup. I live in Florida, no more exhaust inspections in years. I'd prefer to just remove the cat converter altogether. Its the 21st century, why do we still need them? I currently have the stock exhaust, added a K&N cold air intake, gave a little more rumble, I would like just a little more when sitting at a red light next to a Corvette or Challenger. I am thinking just a muffler replacement. The stock 2 1/2" pipes should be fine. Thoughts, opinions, recommendations all welcome.
