A intake won't affect the loudness of your exhaust. Only way to reduce the noise of the exhaust is to put a muffler or resonator on it.

Does intake make your car louder?

Quick answer – Yes. The sound of your car will be louder and more aggressive with a cold air intake. Instead of loudness though, a cold air intake changes the sound of your car engine. You will clearly hear the sound of air flowing into the intake – especially when you rev up the car and then release the throttle.

What makes your exhaust louder?

Aftermarket Exhaust

One of the easiest ways to make your car louder is by getting an aftermarket exhaust kit. The point of getting an aftermarket exhaust is to increase the airflow. This is achieved as performance exhausts make the engine breathe better. As a result, you'll increase your vehicle's horsepower.
