Trunk Tray $79.73 Link   HFP Sport Muffler(Civic Si) [Civic Si] $314.16 by peter panaro Date Added: Monday 09 July, 2007 Hi, Fit anf finish are perfect;--- Quality Item ! ---- Nicer sound than the stock SI muffler.--- Less " boom" at 1500 - 2500 R.P.M. and a smooth, even tone above that.---- The stock muffler seems louder and more "coarse" sounding.---- One thing I don't like is the chrome finisher design; --- I would have liked a rolled edge and a slightly smaller exit size, say about 4 1/2" X 3".
