I know im posting quite a few threads up but i am still learning on subarus so im sorry for that, firstly my eml came on yesterday on the motorway and i presume its because the car has been de-catted and not mapped ( thats my guess ) but today when driving the light went back off so what could this mean, also id like to change my backbox for one a little smaller but does that mean i wont get the nice rumble and also is it ok to get it remapped then change just the back box at a later date? ill enclose a pic just to show how BIG the exhaust is at the minute

 

is it the tailpipe size that bothers you or the size of the box? the box on yours looks quite big and a bit of an eyesore

my old scooby had a raptor backbox which was quite a stubby can with a large pipe and was rather loud due to a full decat

heres some pics



if it is tailpipe size thats bothering you then have a look on here

changing backbox without a remap is fine mate

 

cheers yet again for the info and help matey, to me it just looks TOO big and as im new here i dont now whats best for the car etc, must start reading up on subarus........ alot lol

 

was thinking of getting a prodrive backbox

 

maybe a tad quiet if you like the rumble

 

i do like abit of noise yes mate, what size would you say mine is at a look?

 

Sounds like a milltek is what you need. Perfect size, not too loud on cruise and lovely on wide open throttle.

 

would it be a full system or just backbox matey?

 

Probably would be a turbo back as they are funny with mating up with stock items, or cat back is possible with a spacer after down pipe.

 

Looks like a tornado back box. I had one on my classic, they sound great but are a little on the large side....lol....

 

I had the same with my WRX when I ran it for a while with only a Prodrive Sports Cat on. Mine was a cat below efficiency fault code when read.

You should really get the code read (it will be stored as a historic fault code) just to be on the safe side.
