Also looking at this pipe. now i no its not going to be the top of the range exhaust but i honestly cant afford it. i know the claims are ridculous with 20bhp but surly some gain must be made?

Hi Ash.
The decat section is 2.5 inch and the centre and rear section are 3 inch so they will not fit together.
looks like the decat pipe has a hole for the sensor. Im fitting a similar decat pipe to my 2004 wrx tomorrow so ill let you know if I get a CEL on.

hi Ash,
Fitted it this morning. a bitch of a job as all the nut and bolt heads had rotted away had to cut some of with a hack saw. but worth it in the end. I fitted it with a prodrive back box at the same time and it makes a noticable difference in power an also a nice scoby burble. make sure you have all the gaskets as the only one that was ok to reuse was the one between the downpipe and decat section. it hasnt put any warning lights on but I am using a second hand prodrive ecu so I dont know if they change the software to compensate or not.
