    Comments about Walker Quiet-Flow SS Muffler:

    I installed this on my 2000 Dodge Ram 5.2l tonight. I paid a little extra for the SS one, and am glad I did. The muffler is very solid feeling, and sounds GREAT. The truck hasnt been this quiet in a long time, but you still get the good throaty "glug glug" sound of the V8 engine.

    The only thing I found amiss, but no big deal at all - the muffler is 2-3" shorter than the oem, when put side to side. However, I didnt find this to be a problem at all.

      Installed on my 2001 Dodge Ram 1500 Sport with no problems. Had the old removed and new installed in under an hour. I was often told everyone knew I was coming miles away before and now it sounds quiet.

        Comments about Walker Quiet-Flow SS Muffler:

        My truck is over 14 years old, and the OEM muffler has been getting louder due to rust-through. After searching, I found this Walker replacement and by using a $25 coupon from an earlier purchase, Advance Auto was the cheapest source. Shipping was free and FAST.....installation took only about an hour to remove the old muffler and 10 minutes to install the new one. Nice and quiet now and passes emissions checks.

              A:

              Hi Ed, good question! This Walker Muffler is made of stainless steel and it carries the limited lifetime replacement warranty valid for 90 days from the date of purchase or any longer warranty period that may be printed on your original sales receipt. In addition, you must be the original purchaser of the part and still own the vehicle on which it was installed. This warranty cannot be transferred to anyone at any time. Replacement parts are warranted for 90 days from the date of exchange or the remainder of the warranty period, whichever is longer.
