nope, this post is trying to save him some money
you could just get a decat fitted instead (around £250) and the stage 2 map.
or even cheaper still. get a garage to take off the std downpipe, remove the pre-cat next to the turbo with a hammer(his would still leave the 2nd cat in place for MOTs)
, and go stage 2. im going to give it a try. it wont ever be as good as a performance Dp it it would be a heck of alot better than std
this would cost you abou £35 for a garage to do
