@203 ct : well i have a 97 ex d16y8 so i have the cat under the car only thing is that its straight piped so i wanna get the stock piping i found stock one from a d16y7 but had that doubt about it being sedan or coupe size difference but its not now only thing im figuring out is if i should weld my old cat on this piping or some one told me to put a test pipe but thats illegal so i think im going to put my cat ..
@co671: yea i got some guy on craigslist selling a dc sport 4-1 header for 96-00 civic and thats the same guy with the d16y7 stock exhaust , he said the the header will fit the exhaust piping so the only thing i gotta worry about is the cat ..and i didnt know if it mattered in size for the piping sedan or coupe but i found out it dosent matter,,but about that extended o2 sensor will that matter since my car is ex but ill be getting lx piping ??
thanks guys
