I received my high flow cats from a friend and the box says that they are for a 350z/370z. I am assuming that these are for the HR motor since they included the 370z in there. So these are for the 07+ 350Z and the 370/G37. Will I be able to run these without problems on my 06 Revup DE?

 

they will never match up they have diffrent exhaust manifolds so if wont work unless you also install HR headers

 

Well I guess they will be up for sale soon!

 

DE = 03-06
HR = 07-08 (370 and g37 have same cats as HR)
