What is the best way to increase the growl of my 2012 Camaro
You can make your 2012 Camaro sound louder by changing the muffler. In addition, you can put the Flowmaster exhaust which is three inches and produces quite a deep and loud sound.
Put cardboard in the spokes.
slide a little "cam" in that puppy..make it talk back with a rumble..
Do what the Phantom said with a hi performance muffler the car then Will sound great!
