    Comments about Walker Quiet-Flow SS Muffler:

    I replaced the 10 year old original muffler that failed at the pipe. This one was a close fit with a little tweaking. The bad - after 18 months, it is time to replace it again. It rusted through the body of the muffler, fastest I've ever seen. I live in the salt and snow so if you are from down south, it might not be a problem.

      Comments about Walker Quiet-Flow SS Muffler:

      Glad I read other reviews, replaced muffler on our 2004 Dodge Dakota, this muffler is 3 inches shorter than muffler took off truck, picked up extender pipe before left store. Took awhile to get alignment right as outlet did not align well with our tail pipe. Muffler is in at an angle but with the extender it ended fine.

        Comments about Walker Quiet-Flow SS Muffler:

        This is a nice replacement, it was about 6" shorter then my stock muffler so a short exhaust coupler pipe is needed. My old muffler had an 8" hole in in after replacing, truck is a lot quieter and seems to have a little more power.

        I have it 4/5 stars because it was shorter then my stock muffler, if it was the same length it would have been 5/5 stars.
