        Comments about Walker SoundFX Direct Fit Muffler:

        I saw that this was a Walker muffler and knew that it would be quality. My Lesabre had a big hole in the top of the muffler, but the rest of my system was fine. I did a search on the site and found this,plus a discount on my purchase! Timing is everything, I guess. I was planning to install myself, but, after crawling under the car, found the old one was welded up and very close to some nice brackets, I decided to have a local independent shop do it. It was so simple they only charged $40 to do it and it took 10 mins. I find that Advance Auto store clerks are usually knowledgeable and friendly, and they were when I went to pick this up.

          Good quality muffler at a reasonable price. Was not an exact fit on my 1998 Buick Lesabre as stated. The muffler was about 1 1/2" shorter in length than the stock one. I made up the difference with an adapter.

                    No, this is just the muffler. The clamps have to be purchased seperately.
