I just purchased a 2005 Mustang GT, and I'm looking to improve the sound while still being California emissions legal. Don't know much about exhaust tuning… I love how some cars crackle and pop on liftoff. What can I do to get that? Upgrading performance and cost aren't a big deal to me, I just want it to sound better than stock and give it some more noise.
