I recently purchased this 2015 JKU. The PO installed a K&N air intake system and what appears to be a Flowmaster exhaust. I don't know much about them but what I do know is the Flowmaster is too noisy for my liking. I understand that it's an attempt to get as much air in and out of the engine with as little restriction as possible. Is there an exhaust system I can install that will not be so darn noisy but will give me similar results with the lower restriction?
