Default Cat back for HX vs EX?

I know that if i want to change the headers, i need to buy a cat and some other things.. My question is, will a cat back for an EX/lx fit on my HX, With the stock header/cat setup?

I have an axle back, with stock mid pipe, and i was told to get a cat back system because i want my car louder.

Also what is the stock piping size 2.25?

Well first, the EX and LX have different exhausts so it's not "EX/LX".

That being said, an EX exhaust will fit on your car if you get a test pipe to fill in the gap between the midpipe and the end of the stock header/cat that using the EX exhaust will create.

DX/LX exhaust will be a direct bolt on with no gap.


stock piping is 1.75"

only if you are going to use the stock header/cat.
