I just bought a apexi muffler for my 1994 honda civic lx. I was wondering if anyone knows how to install a muffler? The inlet (the side of the muffler the connects to the stock piping) is only 2.5 inches high, while the stock exhuast 1 inch high. How do i make the muffler fit onto the stock exhuast? Any help about installation of an exhuast would be a great help.
