Hey knowledgeable people, I got stock exhaust piping from my 92 civic si and an exhaust from a 94 integra rs. Now does anyone know the difference between these two? They look like the same diameter, but im not sure. Im puttin a b18b in my civic, does it matter which one i use?

thanks

 

they look the same? do you have just the middle section? the integra one should be longer

 

one should be longer than the other

 

diameter, likely the same or very close.
piping shape, likely the same or very close

nothing a muffler shop couldn't fix in a few minutes.

 

ya just the middle section. which one can or should i use with the b18b?

 

grab urself an OEM type r muffler or an RSX type s muffler.

 

um, ok, that has nothing to do with my question
