well its uk lol?
could it be that the decat the guy before me has fitted is extra length?
so if i was going to go for a 3 inch turbo system back i would need
decat (have it)
Middle pipe (dont think need this has current de-cat reaches the pipe that goes into backbox
Centre section
Backbox

Think i'm correct sure i'll get corrected if not but...
1st cat in downpipe
2nd cat in pipe between downpipe and mid-section
Basically goes...
Downpipe (1st CAT in here)
2nd CAT Section
Midpipe
Backbox

it would appear then that the decat that the owner before me fitted removes both cats
that means all i need now is a decent cat back as as far as i can see i still have the standard centre pipe and prodrive backbox
