Just a quick remove and replace. They did rework the pipe from under the rear axle back as the new muffle is just a little longer. cost me $75 to have it welded on. This will not be a system everyone likes as some will want a louder and raspier sound. After having this on for a few days now I am very glad I went with this muffler. It is not real loud but has a beautiful tone. As a daily driver this sound will not wear you out. The wife is even happy.
