does anyone know if test pipes from an 05 350z will fit on an 07 350z?

i think they will but not really sure if there is any difference. I already know about the spacer for the O2 sensors so the check engine light wont come on.

 

I think the test pipes dont fit but dont quote me on that. I believe the exhaust is what fits both the hr and de motors.

 

Thanks that what im thinking but i dont know if the CATs are different

 

I believe they will not. You'd get more responses if this wasn't in North East.

 

not interchangeable between de and hr.

search. this has been answered many, many times.

 

correct ^ they are not interchangeable
