    8042441 - Flowmaster 40 Series Original Mufflers is rated 4.0 out of 5 by 1.
    Rated 4 out of 5 by from Nice Sound I bought this for my Monte Carlo SS and it was a great upgrade over the stock mufflers. We had to have a muffler shop install as it was not a true bolt in design. Very satisfied with the outcome.
