Ok so I just put on my high flow cats with an x-pipe up to flowmaster 40's. Very loud and sounds great couldnt be happier but I purchased 02 extensions for it from brenspeed since i knew my stock ones wouldnt reach. Well I had a shop fab all this for me and they said the 02s didnt fit. I talked to a guy at a ford dealer who is very knowledgable who i know very well. He said that you have to shave off some of the clips on the outside of the 02 extensions to make them fit right. Was wondering who else has gone through this and how you got your 02's to reach. What website, brands of 02s did you use and did you have to shave off any non needed clips. Please Help!!!!

 

I just cut the O2 wires and extended them myself, it cost me $.20 in stuff I already had and they fit perfectly. Screw the extensions, just do it yourself.
