What can i do so it can sound like a Monster Muscle car.

put a cherry bomb muffler on it instead of the mellow close to stock muffler that is on it.
or if really daring try a glass pack, but you may get into trouble with law if you get too loud

Honestly that depends on how much money you have and are willing to spend. There are a lot of things you can do, more so depending on where you live. It could be as simple as changing exhaust to over-hauling the motor, boring it and putting in a bigger camshaft. Like I said depends on what you want to spend.

ya, you can actually make it in to a muscle car instead of just trying to make it sound like one
