EMPI Single Quiet Pack Muffler Only for #3682 Header

This is the replacement muffler that fits EMPI #3682 header.  It is the replacement for the "standard" quiet pack system (#3647), and may not fit other models of headers.  It has a more "warm" or "moderate" sound, which it is why it is called a quiet pack.  It is not loud or brash sounding like some other exhaust systems, although it is louder than the stock pea-shooter type exhausts.
