The Civic “SI” uses a different engine than your LX. The mufflers may be different.

You could consult a Honda parts counter to see if the mufflers are interchangeable.

You might go to the Advance Auto site and do a cross-reference search by comparing part numbers.
A quick look at the first muffler on the list shows a generic muffler as having the same part number for both the LX and the Si so in theory it should work.
