![Question](https://www.scoobynet.com/images/icons/icon5.gif)
I have been reading on various subaru forums, that if you decat (frontpipe) the CEL light is on the dash? is this true? does a sports cat make a difference to just a straight down pipe? was going to and prefer just a pipe, no sports cat........
As long as its got 2 lamba holes in the pipe, wouldnt have thought the light would be on would it?
ah yes, 2nd cat is already removed![Big Grin](https://www.scoobynet.com/images/smilies/biggrin.gif)
Thats all

You have three cats on a 01 WRX, up-pipe, down pipe & front pipe pipe.
As long as you keep one, the CEL shouldn't come on.
I ran my STi 02 with no cats and it was fine until it was mapped and the extra fuel brought it on now and again.

There one in the up-pipe from headers to turbo, one in the down-pipe from turbo to exhaust & one in the front pipe of the exhaust.
You have three on your wrx as standard unless somebody has already removed the up-pipe one.
