Trim level/part fitment

i have a 96 civic LX. when im looking around for parts, i always see "for EX,Si only or DX only etc, but rarely anything that says LX. Will anything from those models fit my LX, or is it just not worth making parts for? specifically exhaust.

ive gathered that LX and DX are nearly identical(engine and body wise), aside from power steering,windows and locks. is this true?

Yes same engines. As long as you buy and exhaust for a LX,DX 4dr it will work.
