    Talking Thrush welded muffler

    I got myself a Christmas present this past Monday.. a Thrush welded muffler with dual exits coming out the back with chrome tips. Actually a little louder than I wanted, but it sounds great... especially since I only have the 4.8.

    Here's a sound clip from the Thrush website, I think mine sounds better in person of course (Requires Quicktime player to listen)

    I hope it helps fuel mileage maybe just a little bit??

    Dont know if it really helps the mileage yet.. should really know in a couple of tankfuls. What I can tell you is that beyond just sounding good, the get up and go is much more responsive.. doesn't seem to have as much of a sluggish feel.
