IVE JUST GOT A NEW DECATE DOWN PIPE AND REMOVED MY OLD ONE ONLY TO FIND THAT THE SENSOR IN THE OLD PIPE WONT FIT IN THE NEW PIPE AS ITS ABOUT AN 1/2 INCH HOLE IN OLD PIPE AND 3/4 IN NEW PIPE DO THIS HAVE TO BE FITTED OR WHAT PLEASE HELP

 

You don't need that sensor when you decat; assuming you have a blanking plug, just unplug it from the loom.

 

HI THANKS FOR THE INFO MATE ANY IDEA WHERE I COULD GET A BLANKING PLUG FROM?

 

no, but turn your CAPS lock off. if you're stuck, stick an old spark plug in it for now.
