For an HR motor, can you interchange exhausts AND Test pipes for older models??

for example, would an 03+ exhaust and test pipe setup work for an HR motor?

or are there diff flanges/connections?

 

The HR motor has it's catalytic converters located differently than on the DE motors. Hence why 03-06 test pipes/hfc will not fit on HR motors and vice-versa.

However, the rest of the exhaust from the cats back is interchangeable. Bottom line: Any cat-back exhaust will fit any year model 350Z, regardless of HR or DE because both have the same exhaust routing from the cats back.

So to answer your question: the exhaust will work but the test pipes will NOT.

 

Ok Finally an answer.

That def helps...

 

1st thread i see in a while that gives a straight out answer before going down the drain lol

 

well im just going to throw it out their. what about the y pipe?

 

everything but the cats, ae. headers,Ypipe, and exhaust the flanges are the same jus the cats are located diffrently.so when searcheing everythign will work except for testpipes,HFC'S, etc.
