I've tired a few searches terms and I may not be refining my search enough as I am getting way too wide of results so sorry if its out there...

I have a 2001 3.2 S and I know the 2.5 has the o2 sensor in a different spot than the 2.7 and 3.2 engines. Other than the bung required on a 2.5 pipes, are the secondary delete pipes the same or different between a 2.5 and 2.7/3.2 (i.e., bends, diameter, etc)? In other words, would a 2.5 secondary delete pipe work on a 3.2 or do I need 2.7/3.2 pipes?

Thanks!
