mine was 1 7/8" stock when it was replaced with my 2 1/4" piping.

Hmm so swapping to a GT cat-back and muffler would do nothing for an LX

the muffler would sound better, and like Neons, the higher trim got a little better flowing unit than base models.

id just toss the gt muffler on for looks and sound.
