ok i just swaped in a 99-b16a2 into my 92eg and having a lil problems with fiting the exhaust manafold downpipe to the 92 oem exhaust, and were would i fit the cat in there? the cat was part of the old ehaust manfold and now its not ?

 

get a cutt of wheel and a welder and go at it i have a custom exhaust on my sol and my friend did the same as i did on his civic make custom peices

 

isnt that gonna mess up the o2sensor ?
