Quick question!
I found the clamp that has to slide into the rear pipe is way too difficult!
its may of heavy gauge steel, what way I can spread it out?
some said use a wood wedge, I like to hear what other solution!

 

i dont know how far you are into the install ...all you have to do is get the clamp over the 02 sensor bung and it will slide down the rest of the pipe ..a piece of wood will work also you could get some help and pull it apart with a rope in both holes good luck

 

Will put the TH on soon, I'm waiting for the new gasket and buying some tools!
Thanks for the advised!
