I have an 06 Mustang and I'm looking to maximize performance with as little money invested as possible. Which option is better and are there any more cheap modifications that can help maximize horsepower?
as long as it was just today then you're fine. i love Flintstones vitamins.
move mass air intake 3 inch's closer to engine
Golden 5 pretty hit everything on the head.One more thing you can do is install a catback system and an X or H pipe.The less restrictive mufflers and mid-pipe will free up a few more hp,not to mention the sound or tone your car will take on.Google catback exhaust for your year car,you'll find about a hundred of them,good luck.
