"The Flowmaster 80 series muffler sounds great on my 2004 Grand Am Gt. It has a nice low rumble to it when the car idles and isn't that loud at cruising speeds. I did notice an increase in throttle response and horsepower. Overall, i would recommend this product to anyone who wants a nice sound and appearance to their car."
