Hey guys so i got my trust full ti exhaust and all went well and i had a shop weld a bung on it for me to attatch my o2 sensor...later i find out this guy doesnt even know how to weld Ti, and it ends up breaking on my drive home from work one day, i pull over and see a huge hole in my exhaust and the o2 sensor along with the bung and a fat piece of of the exhaust is ripped off. i have found a piece of Ti and im gnna weld it on tomorrow, the thing is, where do i put my O2 sensor? can i get a test pipe to replace my cat and hook it up there? or should i weld a bung to the end of my cat? lemme knwo please thanks!

 

ya u can.. theres evo ix specific test pipes with o2 bungs already welded into them
