  • Q:

    Hello is this a quiet muffler?

      Hi Jayonn, glad to assist you! This 70 Series Big Block II muffler is designed around a large case for maximum volume and efficiency. This is 2 inches narrower than the original Big Block muffler, making it easier to install into tight areas. Other features include a mild, mellow exhaust tone and a resonant tuning chamber for reduced interior sound levels.
